* [AArch64] Prefer "mov" over "orr" to materialize constants.Eli Friedman2019-03-251-2/+2
| | | | | | | | | | | | | 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 materializationAdhemerval Zanella2019-02-011-0/+62
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.
