This patch splits apart PPCISelLowering::LowerFormalArguments_Darwin_Or_64SVR4
into separate versions for the Darwin and 64-bit SVR4 ABIs.  This will
facilitate doing more major surgery on the 64-bit SVR4 ABI in the near future.

Make sure always-inline functions get inlined. <rdar://problem/12423986>

Without this change, when the estimated cost for inlining a function with
an "alwaysinline" attribute was lower than the inlining threshold, the
getInlineCost function was returning that estimated cost rather than the
special InlineCost::AlwaysInlineCost value. That is fine in the normal
inlining case, but it can fail when the inliner considers the opportunity
cost of inlining into an internal or linkonce-odr function. It may decide
not to inline the always-inline function in that case. The fix here is just
to make getInlineCost always return the special value for always-inline
functions. I ran into this building clang with libc++. Tablegen failed to
link because of an always-inline function that was not inlined. I have been
unable to reduce the testcase down to a reasonable size.

X86: fcmov doesn't handle all possible EFLAGS, fall back to a branch for the others.

Otherwise it will try to use SSE patterns and fail horribly if sse is disabled.

Some regression tests which are testing the old jit and are exercising functionality which is both known to be broken and not expected to be fixed in the old jit. To remove these from the regression test output, I've marked them XFAIL (for lit tests) and ifdef'd them out (unit tests). These modifications remove the last long-standing regression test failures from the buildbots (though updating the triple to reflect new ubuntu configuration has temporarily caused some new failures). Tested on x86-64 and ARM Linux.
