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
