tcg/arm: fix branch target change during code retranslation

QEMU uses code retranslation to restore the CPU state when an exception

tcg: Optionally sign-extend 32-bit arguments for 64-bit hosts.

Some hosts (amd64, ia64) have an ABI that ignores the high bits
of the 64-bit register when passing 32-bit arguments. Others
require the value to be properly sign-extended for the type.
I.e. "int32_t" must be sign-extended and "uint32_t" must be...
