Get rid of -O0 hack for GDB for hard-float arm. This was necessary because
libunwind did not support s0-s31. Note that for *most* cases (not all!),
-O0 stops using VFP registers for general purposes.

Also note that this hack was incomplete. We had to compile every functions
with -O0, that can be unwinded. Otherwise, GDB crashed every time exceptions
were raised.
