rin 75fa0b3cd9 GCC 9.3 miscompiles dwarf2{expr,loc}.c with -O2 for earmv5hf{,eb} 
(-O1 is fine). This is a new regression introduced in GCC9.

For everyone's safety, extend -O0 hack to dwarf2{expr,loc}.c for
all arm variants with GCC >= 8.

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.

rin 098da78686 Update gdb/dwarf2expr.c hack for earmv7hf{,eb}; the situation does not 
change even for GCC 9.3 with ``memcmp'' fix.

rin d1007566db Update aes_ccm_tag() hack for m68k. 
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)

mrg 6bfcf96505 build convert_endian() with "no-strict-aliases" optimiser attribute 
to avoid some unknown miscompilation in endian_convert() that causes
ssh to exit on some output (for me, "cc -v".)

note in HACKS.  we should investigate this further if possible as
this seems to indicate a strict aliasing violation.  there certainly
are 32 and 64 bit object arrays being accessed with 8 bit accessors,
but i don't have time currently.
