17591a1080 Machine model: Generate table entries for super-resources. 
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.

9c73b5059b Simplify yaml2obj a bit. 
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.

5a71acca02 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.

d7dc8b56d3 Add some constraints to use of 'returned': 
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.

e3c8c81c87 Un-revert the environ copy in ProgramTest after fixing it on OS X 
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.

58843a7431 AArch64: remove unnecessary check that RS is valid 
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.

since it depends on how to interprete the MDNodes for scalar TBAA and
struct-path aware TBAA.
