Eli Friedman 92d0d13366 [AArch64] Prefer "mov" over "orr" to materialize constants.
This is generally more readable due to the way the assembler aliases
work.

(This causes a lot of test changes, but it's not really as scary as it
looks at first glance; it's just mechanically changing a bunch of checks
for orr to check for mov instead.)

Juergen Ributzka f9660f0712 [AArch64] Use the correct register class for ORR.
While fixing up the register classes in the machine combiner in a previous
commit I missed one.

This fixes the last one and adds a test case.

Juergen Ributzka 31e5b7fb12 Reapply r216805 "[MachineCombiner][AArch64] Use the correct register class for MADD, SUB, and OR.""
This reapplies r216805 with a fix to a copy-past error, which resulted in an
incorrect register class.

Original commit message:
Select the correct register class for the various instructions that are
generated when combining instructions and constrain the registers to the
appropriate register class.

This fixes rdar://problem/18183707.

Juergen Ributzka 25816b0fdd Revert r216805 "[MachineCombiner][AArch64] Use the correct register class for MADD, SUB, and OR."
I think this broke the build bot. Reverting it for now until I have time to take a closer look.
