Use a target-specific VMOVIMM DAG node instead of BUILD_VECTOR to represent
...
NEON VMOV-immediate instructions. This simplifies some things.

Print "dregpair" NEON operands with a space between them, for readability and
...
consistency with other instructions that have lists of register operands.

Reenable DAG combining for vector shuffles. It looks like it was temporarily
...
disabled and then never turned back on again. Adjust some tests, one because
this change avoids an unnecessary instruction, and the other to make it
continue testing what it was intended to test.

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

matches what llvm-gcc and clang now produce.

lowering REG_SEQUENCE instructions.
Insert copies for REG_SEQUENCE sources not killed to avoid breaking later passes.
