  [AMDGPU] Implement 'llvm.get.fpenv' and 'llvm.set.fpenv' (#83906)

Summary:
This patch implements the LLVM floating point environment control
intrinsics and also exposes it through clang. We encode the floating
point environment as a 64-bit value that simply concatenates the values
of the mode registers and the current trap status. We only fetch the
bits relevant for floating point instructions. That is, rounding mode,
denormalization mode, ieee, dx10 clamp, debug, enabled traps, f16
overflow, and active exceptions.
