This series allows hexagon programs to be debugged under qemu user-mode
through LLDB and qemu's gdbstub. LLDB implements the GDB remote serial
protocol, so most of the necessary changes are in the Hexagon part itself.
However, one fix is needed at the arch-independent side too.

Changes in v2:
- Rebased on current master
- Added Taylor's Reviewed-by at patch 5

v1: https://lore.kernel.org/qemu-devel/cover.1680808943.git.quic_mathbern@quicinc.com/
