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.)

[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.)

[AArch64] Optimize floating point materialization

This patch changes isFPImmLegal to return if the value can be enconded
as the immediate operand of a logical instruction besides checking if
for immediate field for fmov.

This optimizes some floating point materization, inclusive values
used on isinf lowering.
