  [SDAG] Use MMO flags in MemSDNode folding

SDNodes with different target flags may now be folded together
rightfully resulting in the assertion in the refineAlignment.
Folding nodes with different target flags may result in the
wrong load instructions produced at least on the AMDGPU.

Fixes: SWDEV-326805
