df78611726 Fixing PR990: http://llvm.org/PR990.
This should unbreak csretcc on Linux & mingw targets. Several tests from
llvm-test should be also restored (fftbench, bigfib).

6e56e2c602 Fixed a bug which causes x86 be to incorrectly match
shuffle v, undef, <2, ?, 3, ?>
to movhlps
It should match to unpckhps instead.

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

3ed469ccd7 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.

ab4022f196 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.

9eca5e814d During vector shuffle lowering, we sometimes commute a vector shuffle to try
to match MOVL (movss, movsd, etc.). Don't forget to commute it back and try
unpck* and shufp* if that doesn't pan out.

  optimal code by failing to identify MOVL (move to lowest element of a
  vector).

ffc0b2663e Eliminate X86ISD::TEST, using X86ISD::CMP instead. Match X86ISD::CMP patterns
using test, which provides nice simplifications like:

-       movl %edi, %ecx
-       andl $2, %ecx
-       cmpl $0, %ecx
+       testl $2, %edi
        je LBB1_11      #cond_next90

There are a couple of dagiselemitter deficiencies that this exposes, they will
be handled later.

bd564bfc63 Start eliminating temporary vectors used to create DAG nodes. Instead, pass
in the start of an array and a count of operands where applicable.  In many
cases, the number of operands is known, so this static array can be allocated
on the stack, avoiding the heap.  In many other cases, a SmallVector can be
used, which has the same benefit in the common cases.

I updated a lot of code calling getNode that takes a vector, but ran out of
time.  The rest of the code should be updated, and these methods should be
removed.

We should also do the same thing to eliminate the methods that take a
vector of MVT::ValueTypes.

It would be extra nice to convert the dagiselemitter to avoid creating vectors
for operands when calling getTargetNode.
