fix PR8961 - a fast isel miscompilation where we'd insert a new instruction
after sext's generated for addressing that got folded. Previously we compiled
test5 into:
_test5: ## @test5
## BB#0:
movq -8(%rsp), %rax ## 8-byte Reload
movq (%rdi,%rax), %rdi
addq %rdx, %rdi
movslq %esi, %rax
movq %rax, -8(%rsp) ## 8-byte Spill
movq %rdi, %rax
ret
which is insane and wrong. Now we produce:
_test5: ## @test5
## BB#0:
movslq %esi, %rax
movq (%rdi,%rax), %rax
addq %rdx, %rax
ret
