[patch committed SH] Add more __sync_* functions to linux-atomic.asm

[Kaz Kojima <kkojima at rr dot iij4u dot or dot jp>]

Hi,

I've applied the attached patch which adds __sync_*_and_fetch_*
and __sync_bool_compare_and_swap_* functions to linux-atomic.asm.
Tested on sh4-unknown-lunux-gnu.

Regards,
	kaz
