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.

Changed sections prefix to allow linker merge them
(PE loader doesn't like too much long-named sections :) )

Fixing truncate. Previously we were emitting truncate from r16 to r8 as
...
movw. That is we promote the destination operand to r16. So
%CH = TRUNC_R16_R8 %BP
is emitted as
movw %bp, %cx.
This is incorrect. If %cl is live, it would be clobbered.
Ideally we want to do the opposite, that is emitted it as
movb ??, %ch
But this is not possible since %bp does not have a r8 sub-register.
We are now defining a new register class R16_ which is a subclass of R16
containing only those 16-bit registers that have r8 sub-registers (i.e.
AX - DX). We isel the truncate to two instructions, a MOV16to16_ to copy the
value to the R16_ class, followed by a TRUNC_R16_R8.
Due to bug 770, the register colaescer is not going to coalesce between R16 and
R16_. That will be fixed later so we can eliminate the MOV16to16_. Right now, it
can only be eliminated if we are lucky that source and destination registers are
the same.

Better implementation of truncate. ISel matches it to a pseudo instruction
...
that gets emitted as movl (for r32 to i16, i8) or a movw (for r16 to i8). And
if the destination gets allocated a subregister of the source operand, then
the instruction will not be emitted at all.
