[ARM] Pass subtarget feature "+no-movt" instead of passing backend option "-arm-use-movt=0". This change is needed since backend options do not make it to the backend when doing LTO and are not capable of changing the behavior of code-gen passes on a per-function basis. rdar://problem/21529937 Differential Revision: http://reviews.llvm.org/D11025 llvm-svn: 242368

Add -fno-movt frontend option, to disable movt/movw on ARM Summary: In rL256641, @davide turned off movt generation by default for FreeBSD. This was because our ld is very old, and did not support the relocations for it. However, Ian Lepore added the support very recently, so we would like to revert rL256641, and replace it with a new `-fno-movt` frontend option. This way, it can be turned off when needed.

Disable generating movt on FreeBSD. It's sort of an hack, but we have no choice. The linker in the base system doesn't handle that correctly (yet). Once FreeBSD will import lld, this can be backed out. Patch by: Andrew Turner! llvm-svn: 256641
