Do not direct commit to contrib/llvm.  Make the change a patch file instead.
Reverts 271025 but still functionally patches it.  Original intent is still
the same.  Pointed out by rdivacky.

MFV:  Only emit movw on ARMv6T2

Building for the FreeBSD default target ARMv6 was emitting movw ASM on certain
test cases (found building qmake4/5 for ARM).  Don't do that, moreover, the AS
in base doesn't understand this instruction for this target.  One would need
to use --integrated-as to get this to build if desired.
