re PR debug/43293 (Invalid unwind info for i?86 -fpic)

Browse Source 
PR debug/43293
	* config/i386/t-i386 (i386.o): Depend on debug.h and dwarf2out.h.
	* config/i386/i386.c: Include debug.h and dwarf2out.h.
	(ix86_file_end): If dwarf2out_do_cfi_asm (), emit .cfi_startproc
	and .cfi_endproc around the pic thunks.
	(output_set_got): For TARGET_DEEP_BRANCH_PREDICTION pic, ensure
	all queued unwind info register saves are saved before the call.
	For !TARGET_DEEP_BRANCH_PREDICTION pic, ensure the call is
	considered as sp-=4 for unwind info and the pop as sp+=4 which
	also clobbers dest, but doesn't actually restore it.
