*** TEST RESULTS FOR COMMIT 1a09b50a463ad005946849540da136b5cbe6237b ***

gdbserver: xtensa: add call0 support
Correctly handle a0- registers on requests from remote gdb. This fixes
'Register 1 is not available'
and subsequent assertion in the remote gdb connecting to the gdbserver:
'findvar.c:291: internal-error: value_of_register_lazy:
Assertion `frame_id_p(get_frame_id (frame))' failed.'
The register structure is the same for windowed and call0 ABIs because
currently linux kernel internally requires windowed registers, so they
are always present.

* linux-xtensa-low.c (xtensa_fill_gregset): Call collect_register
for all registers in a0_regnum..a0_regnum + C0_NREGS range.
(xtensa_store_gregset): Call supply_register for all registers in
a0_regnum..a0_regnum + C0_NREGS range.
