f75b56c1ec 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.

9db3ba4db2 TCG x86/x86-64: use move with zero-extend for loads/stores 
Starting with version 4.3, gcc returns the result of a function in
rax/eax/ax/al instead of rax/eax, depending of the return type. As
a consequence we should use a zero extend moe in TCG loads/stores.

See http://gcc.gnu.org/ml/gcc/2008-01/msg00052.html for more details.

A big thanks to malc who founds the problem and wrote the x86 patch.
