Add a compile-time loop construct to Slang
The basic syntax is:
$for(i in Range(0,99))
{
/* stuff goes here */
}
Note that the exact form is very restrictive. All that you are allowed to change is `i`, `0`, `99` or `/* stuff goes here */`.
As a tiny bit of syntax sugar, the following should work:
$for(i in Range(99))
{
/* stuff goes here */
}
Note that the range given is half-open (C++ iterator `[begin,end)` style).
Both the beginning and end of the range must be compile-time constant expressions that Slang knows how to constant-fold.
The implementation will basically generate code for `/* stuff goes here */` N times, once for each value in the half-open range.
Each time, the variable `i` will be replaced with a different compile-time-constant expression.
While I was working on a test case for this, I also found that our build of glslang had an issue with resource limits, so I fixed that.
Clients will need to build a new glslang to use the fix.
