signals: inline __fatal_signal_pending
__fatal_signal_pending inlines to one instruction on x86, probably two
instructions on other machines. It takes two longer x86 instructions just
to call it and test its return value, not to mention the function itself.
On my random x86_64 config, this saved 70 bytes of text (59 of those being
__fatal_signal_pending itself).
