In GFX10 dlc controlled L1 <https://reviews.llvm.org/L1> cache bypass. In GFX11 it has been repurposed
to control MALL NOALLOC, and glc controls L1 <https://reviews.llvm.org/L1> as well as L0 cache bypass.

Update the documentation and SIMemoryLegalizer accordingly. Set dlc for
nontemporal and volatile accesses.
