graham wihlidal b841d3cb41 Added shader compiler support for [noinline] where available. Informs compiler we want a subroutine created, which can be used to decrease register pressure in certain situations. Code is kept separate, and a set number of registers are used on each call. Should only be used with extensive profiling, as the default inlining behavior is usually best. ...

DXIL:  https://github.com/microsoft/DirectXShaderCompiler/blob/master/tools/clang/test/HLSLFileCheck/hlsl/functions/attribute/noinline.hlsl
SPIRV: https://www.khronos.org/registry/spir-v/specs/unified1/SPIRV.html (DontInline)

Shader code can now use NOINLINE, and also test if it maps to something useful with COMPILER_SUPPORTS_NOINLINE
