x86: Register state saving
This patch introduces a save_registers() function that can be used to
take a snapshot of general purpose registers. This is needed in the
gc_alloc() function to save registers in case we need to enter a
safepoint and need to scan them for references.
We also need a save_signal_registers() function for converting gregset_t
to struct register_state so we can pass register contents to the
gc_safepoint() function.

gc: Pass register state to gc_start() and gc_safepoint()
Save registers in gc_alloc() and pass them to gc_safepoint() so the
latter can scan them for references. Also save the registers in signal
handler and pass them to gc_safepoint(). We need to use pre-allocated
thread-local memory because we can't use the stack or malloc() in the
signal handler.
