c64745ba43 Remove MachineFunction's DefaultDebugLoc member, and make DwarfDebug.cpp 
responsible for figuring out what that's supposed to be on its own.

1d05054dc1 Reapply the removal of SelectionDAGISel's BB, with a fix for the case 
where multiple blocks are emitted; functions which do this need to return
the new BB so that their callers can stay current.

2e6cd50a50 Fix tests for Neon load/store intrinsics to match the i8* types expected by 
the intrinsics.  The reason for those i8* types is that the intrinsics are
overloaded on the vector type and we don't have a way to declare an intrinsic
where one argument is an overloaded vector type and another argument is a
pointer to the vector element type.  The bitcasts added here will match what
the frontend will typically generate when these intrinsics are used.

e52396cb52 Remove the Expr member from IVUsers. Instead of remembering the expression, 
just ask ScalarEvolution for it on demand. This helps IVUsers be more robust
in the case of expressions changing underneath it. This fixes PR6862.

fe24cdbba8 According to A8.6.16 B (Encoding T3) and A8.3 Conditional execution -- A8.3.1 
Pseudocode details of conditional, Condition bits '111x' indicate the
instruction is always executed.  That is, '1111' is a leagl condition field
value, which is now mapped to ARMCC::AL.

Also add a test case for condition field '1111'.

152b2bc046 This is horrible. Split the difference, and declare 'environ' on all non-Darwin 
platforms to unbreak the darwin and linux builds. The BSD folks should feel
free to change the #if, if this breaks them.

22b58ac393 make Program::Execute use posix_spawn on systems that support it, 
as it is more efficient than fork/exec.

Thanks to Eric for adding the autoconf check.  It would be nice if
a cmake guru could add a cmake check for posix_spawn as well.
