Christudasan Devadasan 229e118559 [AMDGPU] Codegen support for constrained multi-dword sloads (#96163) ...

For targets that support xnack replay feature (gfx8+), the
multi-dword scalar loads shouldn't clobber any register that
holds the src address. The constrained version of the scalar
loads have the early clobber flag attached to the dst operand
to restrict RA from re-allocating any of the src regs for its
dst operand.
