Fabian Ritter b95a6c750c [AMDGPU] Remove special cases in TTI::getMemcpyLoop(Residual)LoweringType (#125507) ...

These special cases limit the width of memory operations we use for
lowering memcpy/memmove when the pointer arguments are 2-aligned or in
the LDS/GDS.

I found that performance in microbenchmarks on gfx90a, gfx1030, and
gfx1100 is better without this limitation.
