[SPIR-V] Initial support for SPIR-V in `gpuintrin.h` (#174910)

Summary:
https://github.com/llvm/llvm-project/pull/174862 and
https://github.com/llvm/llvm-project/pull/174655 provided the intrinsics
required to get the fundamental operations working for these. This patch
sets up the basic support (as far as I know).

This should be the first step towards allowing SPIR-V to build things
like the LLVM libc and the OpenMP Device Runtime Library. The
implementations here are intentionally inefficient, such as not using
the dedicated SPIR-V opcode for read firstlane. This is just to start
and hopefully start testing things later.

Would appreciate someone more familiar with  the backend double-checking
these.

[clang][CodeGen] Fix ConstantInt::get for i1 in EmitScalarPrePostIncDec (#175152)

In ScalarExprEmitter::EmitScalarPrePostIncDec we create ConstantInt
values that are either 1 or -1. There is a special case when the type is
i1 (e.g. for unsigned _BitInt(1)) when we need to be able to create a
"i1 true" value for both inc and dec.

To avoid triggering the assertions added by the pull request #171456 we
now treat the ConstantInt as unsigned for increments and as signed for
decrements.
