4fec4077fc AArch64/ARM64: add support for :abs_gN_s: MOVZ modifiers 
We only need assembly support, so it's fairly easy.

d4b4f400e8 AArch64/ARM64: disentangle the "B.CC" and "LDR lit" operands 
These can have different relocations in ELF. In particular both:

    b.eq global
    ldr x0, global

are valid, giving different relocations. The only possible way to distinguish
them is via a different fixup, so the operands had to be separated throughout
the backend.

present.

dc71f098bc MC: move ARM64 test from AArch64 directory 
The test was changed from aarch64 to arm64 but not moved.  The test would fail
if the backend was not built.

7582d8d76f [AArch64 NEON] Accept both #0.0 and #0 for comparing with floating point zero in asm parser. 
For FCMEQ, FCMGE, FCMGT, FCMLE and FCMLT, floating point zero will be
printed as #0.0 instead of #0. To support the history codes using #0,
we consider to let asm parser accept both #0.0 and #0.
