  clang: Add elementwise bitreverse builtin

Add codegen for llvm bitreverse elementwise builtin
The bitreverse elementwise builtin is necessary for HLSL codegen.
Tests were added to make sure that the expected errors are encountered when these functions are given inputs of incompatible types, or too many inputs.
The new builtin is restricted to integer types only.
