X86: correct tail return address calculation

Due to the weird and wondeful usual arithmetic conversions, some
calculations involving negative values were getting performed in
uint32_t and then promoted to int64_t, which is really not a good
idea.

Patch by Katsuhiro Ueno.

X86: specify CPU on new test to fix atom buildbot

Apparently Atoms use lea for stack adjustment, which we weren't
looking for.

X86: Turn fp selects into mask operations.

double test(double a, double b, double c, double d) { return a<b ? c : d; }

before:
_test:
	ucomisd	%xmm0, %xmm1
	ja	LBB0_2
	movaps	%xmm3, %xmm2
LBB0_2:
	movaps	%xmm2, %xmm0

after:
_test:
	cmpltsd	%xmm1, %xmm0
	andpd	%xmm0, %xmm2
	andnpd	%xmm3, %xmm0

Build with the $RDYNAMIC flag on Darwin as well as other platforms.

Part of <rdar://problem/14620988>

Remove "lto_on_osx" xfails, now that -rdynamic works on Darwin.

Note that this will require a recent version of the linker for Darwin
builds with LTO to pass these tests.

Add the saving of S2. This is needed for some of the floating point
helper functions. This can be optimized out later when the remaining
parts of the helper function work is moved into the Mips16HardFloat pass.
For now it forces us to use the 32 bit save/restore instructions instead
of the 16 bit ones.
