results. (#1061)

Work on #1059
The `%` operator in the Slang implementation had several issues, and this change tries to address some of them:
* Renamed most occurences of "mod" describing this operator to be "rem" for "remainder" to better match its semantics in HLSL
* Split the operator into distinct integer and floating-point variants (`IRem` and `FRem`) to simplify having different codegen for the two
* Added floating-point variants of `operator%` and `operator%=` to the stdlib.
* Added custom C++ codegen for `kIROp_FRem` such that it maps to the standard C/C++ `remainder()` function
* Added custom GLSL codegen so that `kIROp_FRem` maps to the GLSL `mod()` function (which isn't correct...)
* Added a test case to confirm that D3D11, D3D12, and CPU targets all agree on the definition of floating-point `%`
* Fixed `render-test-tool` to allow a negative integer in a `data=...` specification. This didn't end up being used in the final test, but still seems like a good fix.
* Added a customized baseline for the Vulkan flavor of that test to confirm that we are *not* compiling correctly to SPIR-V just yet
Addressing the correctness of the output for GLSL/SPIR-V will have to come as a later change given that the operation we want is not exposed directly by unextended GLSL.

It was possible for a recursive call to `tryRemoveTriviailPhi` to remove/replace a phi node that was already in a list of removal candidates to be processed. When the recursive call returned and that candidate was again considered, its operands would have already been cleared, leading to an assertion failure.
This case is what was coming up in practice in a user shader, although I have not been able to reproduce the failure with a more minimal synthetic test yet.
This change also changes the SSA creation logic to avoid a runtime crash in the case of a trivial phi that only references itself (which was how the above bug surfaced to the user). The "fix" there is not ideal (it leaves a trivial phi behind), but should be enough to retain semantic correctness if user code ever causes that (corneer-case) code path to execute. It is also expected that such a trivial phi would be removed in later DCE passes anyway.

Removed CPU_EXECUTE test style -as tested via the now cross platform render-test
* Split out execution from setup for execution to improve perf.

* Revisions to "new" Slang API based on use in Falcor
As I've been integrating the new/revised Slang API (using the "COM-lite" interfaces) I've run into some cases where the API was either missing features or didn't really work as originally implemented. This change fixes the gaps/problems that came up.
There are two main things here:
1. Some of the routines that returned an `IComponentType*` as a function result weren't actually doing anythign to retain the object they returned (e.g., putting it into a cache). Leaving aside the question of whether we need to add that caching layer, it made sense to instead have the return be through an output argument. Discussion after the initial iteration of the COM-lite API came around to the point that properly reference-counting objects that get returned would be useful if we ever decide we don't like having ever-expanding memory usage for caches of specialized/composed component types.
2. There was no way with the existing API to get at an `IComponentType` that represents an entry point produced during compilation, so that a user could include it in their own composition. This change alters `spCompileRequest_getProgram` to return the global program *without* the entry points, and adds a separate `spCompileRequest_getEntryPoint`. This design lets an application compose whatever combination/layout they want, rather than being stuck with a pre-designed composition baked into the compiler.

We already have test cases that compare `slangc` and `fxc` output (in DXBC assembly). This change adds an option to do the same basic thing for `slangc` and `dxc` (comparing DXIL output).
This isn't being enabled for any of our regression tests right now. It is mostly just a useful feature to have when reproducing customer issues that relate to DXIL output in cases where `dxc` can produce a baseline to compare against to isolate the problem.

* Update signatures for Shader Model 6 functions
We originally culled out list of Shader Model 6 function prototypes from some combination of MSDN and the dxc wiki, but this was when things were in a pre-release state and the names of many functions changed (as well as some functions being added/removed).
For this change, I initially tried to look at MSDN, but the documentation there was internally inconsistent and included things like misspellings in function names (which I *hoped* weren't accurate to the real implementation). Instead, I looked at the meta-program input that dxc uses to generate its intrinsic definitions and used that to discover the updated function names along with what was added/removed, a few signature differences, and some extra functions that don't even seem to be documented at all on MSDN>
These have *not* been tested in any meaningful way, so this is really a best-effort thing. Given that most of the old functions had the wrong names there was no way for them to be used in working code anyway, so this is unlikely to cause breakage.
* fixup: quadLaneID is a uint

* Split up prelude into scalar intrinsics, and types.
Use slang.h for main header.
slang-cpp-prelude.h can now just include what it needs (relative to prelude directory) and define the few remaining things/work arounds.
* Fix typo.

The set of supported operations in front-end constant folding was very limited: `+`, `-`, `*`, `/`, and `%`.
This meant that enum declarations like:
```
enum MyBits
{
A = 1 << 0,
B = 1 << 1,
C = A | C,
}
```
would fail to compile, with a claim that the expressions like `1 << 0` aren't compile-time constants.
This change adds `<<`, `>>`, `&`, `|`, and `^` to the list of integer operations we will cosntant-fold in the front-end. It also changes one of the declarations in the existing test case for `enum`s to use the added functionality.
Note that this change does *not* address the more deep-seated problems with our approach to constant-folding in the front-end. It does not change the constant folding to rely on IR machinery, or to allow for more general `constexpr` functions, and it does not address the fact that constant-folding is currently applied without paying attention to the type (and thus precision) of the original expression.
