Remove arm_apcscc from the test files. It is the default and doing this

matches what llvm-gcc and clang now produce.

Recognize more BUILD_VECTORs and VECTOR_SHUFFLEs that can be implemented by
...
copying VFP subregs. This exposed a bunch of dead code in the *spill-q.ll
tests, so I tweaked those tests to keep that code from being optimized away.

Besides removing phi cycles that reduce to a single value, also remove dead
...
phi cycles. Adjust a few tests to keep dead instructions from being optimized
away. This (together with my previous change for phi cycles) fixes Apple
radar 7627077.

Dynamic stack realignment use of sp register as source/dest register
...
in "bic sp, sp, #15 " leads to unpredicatble behaviour in Thumb2 mode.
Emit the following code instead:
mov r4, sp
bic r4, r4, #15
mov sp, r4
