Jian Cai 0e1accd0f7 [AArch64] Support expression results as immediate values in mov ...

Summary:
This patch adds support of using the result of an expression as an
immediate value. For example,

0:
.skip 4
 1:
mov x0, 1b - 0b

is assembled to

mov x0, #4

Currently it does not support expressions requiring relocation unless
explicitly specified. This fixes PR#45781.
