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.)

Adhemerval Zanella 8a595b1d2e [AArch64] Refactor floating point materialization. NFC
It splits the login of actual instruction emission away from the logic
that figures out the appropriate sequence on AArch64ExpandPseudo::expandMOVImm.
The new function AArch64_IMM::expandMOVImm, which return the list of the 
instructions to materialize the immediate constant, is implemented on a 
separated unit because it will be used in a subsequent patch to optimize
floating point materialization.
