Fix cmake build without native target selected.
The cmake (+ MSVC) build is broken if you don't select your native
target.
e.g. 'cmake -D LLVM_TARGETS_TO_BUILD="MyNonNativeTarget" .'
This is because cmake currently sets the LLVM_NATIVE_* definitions
regardless of whether the native target is selected (causing build
errors).

For ARM stack frames that utilize variable sized objects and have either
large local stack areas or require dynamic stack realignment, allocate a
base register via which to access the local frame. This allows efficient
access to frame indices not accessible via the FP (either due to being out
of range or due to dynamic realignment) or the SP (due to variable sized
object allocation). In particular, this greatly improves efficiency of access
to spill slots in Thumb functions which contain VLAs.
