Subject: First Slang LLVM integration (#1934)

* #include an absolute path didn't work - because paths were taken to always be relative.

* First integration with 'slang-llvm'.

* Fix project.

* Fix test output.

* First pass assert support.

* Add inline impls for min and max.

* Add abs inline abs impl for llvm.

* Make abs not use ternary op

* Fix typo in slang-llvm.h

* Sundary fixes to make remaining tests using llvm backend pass.
