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.

(-O1 is fine). This is a new regression introduced in GCC9.

GCC 9.3 seems to be able to compile rtree.c with -O2:
- No new regressions in ATF.
- System survives over a night, at least, under heavy loads.
On the other hand, unfortunately, GCC 9.3 still miscompiles tcache.c
with -O2 or -O1. For example, even ``gcc -g hello.c'' fails with ICE
if tcache.c is compiled with -O[12] in libc.

Even with ``memcmp fix'', GCC 9.4 miscompiles this function for -O[12].
But the situation was slightly changed from that with GCC 8.3:
* -O0 and -O1 work but -O2 fails for 68060 and 68040 (real hardware)
* -O0 and -O2 work but -O1 fails for 68020 and 68010 (TME)
