cmd/compile: add DWARF reg defs & fix 32-bit location list bug

Browse source 
Before DWARF location lists can be turned on, 3 bugs need
fixing.

This CL addresses two -- lack of register definitions for
various architectures, and bugs on 32-bit platforms.
The third bug comes later.

Passes
GO_GCFLAGS=-dwarflocationlists ./run.bash -no-rebuild
(-no-rebuild because the map dependence causes trouble)
