For PR786:
...
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

1. Clean up code due to changes in SwitchTo*Section(2)
...
2. Added partial debug support for mingw\cygwin targets (the same as
Linux\ELF). Please note, that currently mingw\cygwin uses 'stabs' format
for storing debug info by default, thus many (runtime) libraries has
this information included. These formats shouldn't be mixed in one binary
('stabs' & 'DWARF'), otherwise binutils tools will be confused.

Encode pc-relative conditional branch offset as pc+(num of bytes / 4). The

asm printer will print it as offset*4. e.g. bne cr0, $+8.
The PPC code emitter was expecting the offset to be number of instructions, not
number of bytes. This fixes a whole bunch of JIT failures.
