src/commonlib/lz4_wrapper: Correct inline asm for unaligned 64-bit copy
Rewrite inline assembly for ARMv7+ to correctly annotate inputs and
outputs. On ARM GCC 6.1.1, this causes assembly output to change from
the incorrect
@ r0 is allocated to hold dst and x0
@ r1 is allocated to hold src and x1
ldr r0, [r1] @ clobbers dst!
ldr r1, [r1, #4]
str r0, [r0]
str r1, [r0, #4]
to the correct
@ r0 is allocated to hold dst
@ r1 is allocated to hold src and x1
@ r3 is allocated to hold x0
ldr r3, [r1]
ldr r1, [r1, #4]
str r3, [r0]
str r1, [r0, #4]
Also modify checkpatch.pl to ignore spaces before opening brackets when
used in inline assembly.
