Andrew Burgess 6a9ad81c44 gdb/riscv: use a single regset supply function for riscv fbsd & linux 
The RISC-V x0 register is hard-coded to zero.  As such neither Linux
or FreeBSD supply the value of the register x0 in their core dump
files.

For FreeBSD we take care of this by manually supplying the value of x0
in riscv_fbsd_supply_gregset, however we don't do this for Linux.  As
a result after loading a core file on Linux we see this behaviour:

  (gdb) p $x0
  $1 = <unavailable>

In this commit I make riscv_fbsd_supply_gregset a common function that
can be shared between RISC-V for FreeBSD and Linux, this resolves the
above issue.

There is a similar problem for the two registers `fflags` and `frm`.
These two floating point related CSRs are a little weird.  They are
separate CSRs in the RISC-V specification, but are actually sub-fields
of the `fcsr` CSR.

As a result neither Linux or FreeBSD supply the `fflags` or `frm`
registers as separate fields in their core dumps, and so, after
restoring a core dump these register are similarly unavailable.

In this commit I supply `fflags` and `frm` by first asking for the
value of `fcsr`, extracting the two fields, and using these to supply
the values for `fflags` and `frm`.
