af5643de3c [VECTOR-SELECT] Address one of the bugs in pr10902. 
Vector SetCC result types need to be type-legalized.
This code worked before because scalar result types are known to be legal.

a675de9fac Change: 
assert(!"error message");

To:

  assert(0 && "error message");

which is more consistant across the code base.

c94573ded6 Lower ARM adds/subs to add/sub after adding optional CPSR operand. 
This is still a hack until we can teach tblgen to generate the
optional CPSR operand rather than an implicit CPSR def. But the
strangeness is now limited to the selection DAG. ADD/SUB MI's no
longer have implicit CPSR defs, nor do we allow flag setting variants
of these opcodes in machine code. There are several corner cases to
consider, and getting one wrong would previously lead to nasty
miscompilation. It's not the first time I've debugged one, so this
time I added enough verification to ensure it won't happen again.

2599a202e2 Make sure IPSCCP never marks a tracked call as overdefined in SCCPSolver::ResolvedUndefsIn. If we do, we can end up in a situation where a function is resolved to return a constant, but the caller is marked overdefined, which confuses the code later.

1fbce6b02d lib/Linker: add support of deps which does not end with ".so". 
It happens (for example) when you want to have a dependency on the .so
with the specific version, like liblzma.so.1.0.0 or
libcrypto.so.0.9.8.

9e1900bcf7 Omit extracting a loop if one of the exits is a landing pad. 
The landing pad must accompany the invoke when it's extracted. However, if it
does, then the loop isn't properly extracted. I.e., the resulting extraction has
a loop in it. The extracted function is then extracted, etc. resulting in an
infinite loop.

817b059c93 Remove the hack to check UNAME_RELEASE when identifying the Darwin version. 
This was only needed to locate llvm-gcc's installation directory when clang
falls back to run llvm-gcc for i386 kexts.  As of clang svn r140187, we're
now just searching paths with several different Darwin versions on either
side of the current version, so this is no longer needed.

1ac89f2739 When extracting a basic block that ends in an 'invoke' instruction, we need to 
extract its associated landing pad block as well. However, that landing pad
block may have more than one predecessor. So split the landing pad block so that
individual landing pads have only one predecessor.

This type of transformation may produce a false positive with bugpoint.

bfac89c238 Restore hasPostISelHook tblgen flag. 
No functionality change. The hook makes it explicit which patterns
require "special" handling. i.e. it self-documents tblgen
deficiencies. I plan to add verification in ExpandISelPseudos and
Thumb2SizeReduce to catch any missing hasPostISelHooks. Otherwise it's
too fragile.

53aeb9f663 ARM isel bug fix for adds/subs operands. 
Modified ARMISelLowering::AdjustInstrPostInstrSelection to handle the
full gamut of CPSR defs/uses including instructins whose "optional"
cc_out operand is not really optional. This allowed removal of the
hasPostISelHook to simplify the .td files and make the implementation
more robust.
Fixes rdar://10137436: sqlite3 miscompile
