Subject: [AArch64] Remove .data_region directive from AArch64.
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=287cc35cd7d9492751e5b000d98a80d5c9a50e0a

[AArch64] Remove .data_region directive from AArch64.

.data_region is only used in Darwin, so it shouldn't be generated
for other OS. Currently AArch64 doesn't support darwin yet, so
I removed it from AArch64. When Darwin is supported someday, we can
add it back and associate it with Darwin.
