immediate in small code model. The JIT cannot ensure GV's are placed in the
lower 4G.
- Some preliminary support for large code model.

This fixes PR1029 and Regression/CodeGen/X86/x86-64-asm.ll

- Proper support for both small static and PIC modes under X86-64
- Some (non-optimal) support for medium modes.

Added X86 specific nodes X86ISD::FMAX, X86ISD::FMIN instead.

This fixes PR996.

This should unbreak csretcc on Linux & mingw targets. Several tests from
llvm-test should be also restored (fftbench, bigfib).

It should match to unpckhps instead.

Added proper matching code for
shuffle v, undef, <2, 3, 2, 3>

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.

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.
