I know what would be cool! We should align the compact unwind section because
aligned data access is faster.

Add more tests for r179925 to verify correct handling of signext/zeroext; strengthen condition check to require actual MVT::i32 virtual register types, just in case (no actual functionality change)

DAGCombine should not aggressively fold SEXT(VSETCC(...)) into a wider VSETCC without first checking the target's vector boolean contents.
This exposed an issue with PowerPC AltiVec where it appears it was setting the wrong vector boolean contents.  The included change
fixes the PowerPC tests, and was OK'd by Hal.

Testing for _XCR_XFEATURE_ENABLED_MASK instead of a specific MSVC version because some MSVC 2010 SP1 installations do not have the _xgetbv intrinsic.  Patch thanks to Serge Pavlov!

LoopVectorizer: Fix 15830. When scalarizing and unrolling stores make sure that the order in which the elements are scalarized is the same as the original order.
This fixes a miscompilation in FreeBSD's regex library.

1) Disallow 'returned' on parameter that is also 'sret' (no sensible semantics, as far as I can tell).
2) Conservatively disallow tail calls through 'returned' parameters that also are 'zext' or 'sext' (for consistency with treatment of other zero-extending and sign-extending operations in tail call position detection...can be revised later to handle situations that can be determined to be safe).

This is a new attribute that is not yet used, so there is no impact.

Add basic zlib support to LLVM. This would allow to use compression/uncompression in selected LLVM tools.

AArch64 always demands a register-scavenger, so the pointer should never be
NULL. However, in the spirit of paranoia, we'll assert it before use just in
case.

The tag is of type TBAANode when flag EnableStructPathTBAA is off.

Move implementation of MDNode::getMostGenericTBAA to TypeBasedAliasAnalysis.cpp
since it depends on how to interprete the MDNodes for scalar TBAA and
struct-path aware TBAA.

name computation is expensive, this helps save about 25% of the time spent in
this function.

Changed back (relative to commit 179786) the operations executed when extract(cast) is transformed to cast(extract). It uses the Builder class as before. In addition the result node is added to the Worklist, so all the previous extract users will become the new scalar cast users.
