On the ruby side, this fixes a crash for methods with 39 or more
parameters. We used to miscomp those entry points due to Insn::Lea
picking ADDS which cannot reference SP:
# set method params: 40
mov x0, #0xfee8
movk x0, #0xffff, lsl #16
movk x0, #0xffff, lsl #32
movk x0, #0xffff, lsl #48
adds x0, xzr, x0
Have Lea work for all i32 displacements and avoid involving the split
pass. Previously, direct use of Insn::Lea directly from the user (as
opposed to generated by the split pass for some memory operations)
wasn't split, so being able to handle the whole range in arm64_emit()
was implicitly required. Also, not going through split reduces register
pressure.
