aarch64/gdbserver: fix floating point registers display
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

* linux-aarch64-low.c (AARCH64_FPSR_REGNO): New define.
(AARCH64_FPCR_REGNO): Likewise.
(AARCH64_NUM_REGS): Update to include fpsr/fpcr registers.
(aarch64_fill_fpregset): Add missing fpsr/fpcr registers.
(aarch64_store_fpregset): Likewise.
