Driver: use GNU::Link for the Generic_GCC toolchain

This changes the behaviour of the driver for linking to match that of the
Generic_GCC::Assemble.    The default link should use "ld" rather than "gcc" for
the linker as gcc does.  This avoids the unnecessary round-tripping through gcc.
It also is much more reasonable behaviour from the user's perspective.  This
should have been updated with SVN r195554 which changed the behaviour of
Generic_GCC::Assemble.

The gcc_forward test needs to be updated to mark the fact that -march is a flag
for GCC not ld.  This was updated as a typo fix, but added a check for a flag
that is not a link flag.

The bindings test covers the change for testing, and thus no new test was added.

[X86] Improve the selection of SSE3/AVX addsub instructions.

This patch teaches the backend how to canonicalize a shuffle vectors
according to the rule:

 - (shuffle (FADD A, B), (FSUB A, B), Mask) ->
       (shuffle (FSUB A, -B), (FADD A, -B), Mask)

Where 'Mask' is:
  <0,5,2,7>            ;; for v4f32 and v4f64 shuffles.
  <0,3>                ;; for v2f64 shuffles.
  <0,9,2,11,4,13,6,15> ;; for v8f32 shuffles.

In general, ISel only knows how to pattern-match a canonical
'fadd + fsub + blendi' dag node sequence into an ADDSUB instruction.

This new rule allows to convert a non-canonical dag sequence into a
canonical one that will be matched by a single ADDSUB at ISel stage.

The idea of converting a non-canonical ADDSUB into a canonical one by
swapping the first two operands of the shuffle, and then negating the
second operand of the FADD and FSUB, was originally proposed by Hal Finkel.
