Fix PR46932: Block auto increment on frame pointer
Block auto increment on frame pointer references. This is never
beneficial since the SFP expands into SP+C or FP+C during register
allocation. The generated code for the testcase is now as expected:
str x30, [sp, -32]!
strb w0, [sp, 31]
add x0, sp, 31
bl foo3
ldr x30, [sp], 32
