arm64 front end: add early-writeback handling for w (32 bit int) and q (128 bit) stores.
Clang 6.0.1 creates instructions of the form str wX, [sp,#-N] and str qX,
[sp,#-N], and the lack of early writeback causes many false positive errors
from Memcheck, plus it potentially breaks the segfault-based main-thread stack
extension mechanism. This commit adds support for them, using the same scheme
with which existing cases are handled.
