DebugInfo: Don't emit a 'global variable' when a static member declaration is referenced without a definition, just ensure the enclosing class (with the static member declaration) is emitted.
Addresses PR21511 by emitting appropriate metadata rather than

[X86] Improved lowering of v4x32 build_vector dag nodes.
This patch improves the lowering of v4f32 and v4i32 build_vector dag nodes
that are known to have at least two non-zero elements.
With this patch, a build_vector that performs a blend with zero is
converted into a shuffle. This is done to let the shuffle legalizer expand
the dag node in a optimal way. For example, if we know that a build_vector
performs a blend with zero, we can try to lower it as a movq/blend instead of
always selecting an insertps.
This patch also improves the logic that lowers a build_vector into a insertps
with zero masking. See for example the extra test cases added to test sse41.ll.

[ADT] Fix PR20728 - Incorrect APFloat::fusedMultiplyAdd results for x86_fp80.
As detailed at http://llvm.org/PR20728, due to an internal overflow in
APFloat::multiplySignificand the APFloat::fusedMultiplyAdd method can return
incorrect results for x87DoubleExtended (x86_fp80) values. This commonly
manifests as incorrect constant folding of libm fmal calls on x86. E.g.
fmal(1.0L, 1.0L, 3.0L) == 0.0L (should be 4.0L)
This patch fixes PR20728 by adding an extra bit to the significand for
intermediate results of APFloat::multiplySignificand, avoiding the overflow.

Fix a temporary MDNode leak.
While emitting debug information for function forward decalrations, we
create DISubprogram objects that aran't stored in the AllSubprograms
list, and thus won't get finalized by the DIBuilder. During the DIBuilder
finalize(), the temporary MDNode allocated for the DISubprogram
Variables field gets RAUWd with a non temporary DIArray. For the forward
declarations, simply delete that temporary node before we delete the
parent node, so that it doesn't leak.

R600/SI: Make SIInstrInfo::isOperandLegal() more strict
A register operand that has a common sub-class with its instruction's
defined register class is not always legal. For example,
SReg_32 and M0Reg both have a common sub-class, but we can't
use an SReg_32 in instructions that expect a M0Reg.
This prevents the llvm.SI.sendmsg.ll test from failing when the fold
operand pass is added.
