tcg-i386: Implement small forward branches.
There are places, like brcond2, where we know that the destination
of a forward branch will be within 127 bytes.
Add the R_386_PC8 relocation type to support this. Add a flag to
tcg_out_jxx and tcg_out_brcond* to enable it. Set the flag in the
brcond2 label_next branches; pass along the input flag otherwise.
