[PATCH 19/27] gdb: %p => host_address_to_string, dump_for_expression

Use host_address_to_string in dump_for_expression, which always
renders a host pointer with a "0x" prefix regardless of the C runtime,
as GDB does elsewhere for this reason.

Tested on x86_64-pc-linux-gnu and x86_64-pc-windows-msvc.
