Ben Shi 9be1921042 cmd/internal/obj/arm64: optimize constant pool
"MOVD $0xaaaaaaaa, R2"
"MOVD $-0x55555555, R3"

For the above instructions, 64-bit constants 0x00000000 aaaaaaaa
and 0xffffffff aaaaaaab are stored in the constant pool.

This CL optimizes them to
"MOVWU $0xaaaaaaaa, R2"
"MOVW $-0x05555555, R3"
and 32-bit constants 0xaaaaaaaa and 0xaaaaaaab are stored in the
constant pool.

There is a little size reduction (about total 5KB) in both the go
executable and the library files.
