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

Super-resources and resource groups are two ways of expressing
overlapping sets of processor resources. Now we generate table entries
the same way for both so the scheduler never needs to explicitly check
for super-resources.

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)

The COFFParser now contains only a COFFYAML::Object and the string table
(which is recomputed, not serialized).

The structs in COFFParser now all begin with a Header field with what is
actually on the COFF object. The other fields are things that are semantically
part of the struct (relocations in a section for exmaple), but are not actually
represented that way in the object file.

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.

This was r180041 and r180046, which was reverted in r180066.
Re-committing this should fix the dragonegg bootstrap, which I presume
needs LD_LIBRARY_PATH to be propagated to the child.

Tested on Linux, Windows, and Mac OS 10.6.
