Subject: make arm-use-movt available for all ARM
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=14c41370e36068ae25c871d5bd8f99f92bbb7d45;p=oota-llvm.git

make arm-use-movt available for all ARM

Before this patch this flag is IOS specific, but is also
useful for bare project like bootloaders / kernels etc,
since movw / movt prevents simple relocation. Therefore
make this flag more commonly available.

note: this patch depends on a similiar rename in clang
