If we re-enter runtime via an interceptor when in_blocking_func is set,
temporary reset in_blocking_func around the interceptor and restore it back

[HLSL] add ceil library function

This change exposes the ceil library function for HLSL,
excluding long, int, and long long doubles.
Ceil is supported for all scalar, vector, and matrix types.

Long and long long double support is missing in this patch because those types
don't exist in HLSL. Int is missing because the ceil function only works on floating type arguments.

the include guard optimization in the --trace-includes output, which
breaks the use case that we were trying to use it for.

However, Clang does support the -fshow-skipped-includes flag, which
does exactly what we need and will result in an accurate include
