It appears that FXC and DXC do some validation post dead-code-elimination.
These tests have been updated so that the return value is assigned to a storage buffer, ensuring that all validation is performed.
Many DXC tests are affected by https://github.com/microsoft/DirectXShaderCompiler/issues/5082, which have been SKIP'ed.

This CL updates the templates in the StringStream to match more types.
All of the internal `operator<<` methods have been converted over to
StringStream. The precision was increased in order to better match the
