Some tests expect the the target is aarch64, but checking target
triplet is not accurate, because target triplet can be aarch64 but
the program is in arm (or aarch32) state.
This patch addes a new proc is_aarch64_target which returns true
if the target is on aarch64 state.

* gdb.arch/aarch64-atomic-inst.exp: Check is_aarch64_target
instead of istarget "aarch64*-*-*".
* gdb.arch/aarch64-fp.exp: Likewise.
* gdb.base/float.exp: Likewise.
* gdb.reverse/aarch64.exp: Likewise.
* lib/gdb.exp (is_aarch64_target): New proc.
When using aarch64 gdb with gdbserver, floating point registers are
not correctly displayed, as below:
(gdb) info registers fpsr fpcr
fpsr <unavailable>
fpcr <unavailable>
To fix these problems, the missing fpsr and fpcr registers are added
when floating point registers are read/write
Add test for aarch64 floating point
