Rafael Espindola c90a32a4e6 AnalyzeBranch modifies the bb, but we don't want to modify a bb with 
eh edges. Swap the order of the checks to avoid it.

Roman Divacky 4b5665a1f7 Fix emission of PPC64 assembler on non-darwin platforms by splitting 
VK_PPC_{HA,LO}16 into darwin and gas variants.

Darwin wants {ha,lo}16(symbol) while gnu as wants symbol@{ha,l}.

John McCall fc1ca36866 SplitCriticalEdge can sometimes split the edge from an invoke to a landing 
pad, separating the exception and selector calls from the new lpad.  Teaching
it not to do that, or to properly adjust the CFG afterwards, is out of
scope because it would require the other edges to the landing pad to be split
as well (effectively).  Instead, just recover from the most likely cases
during inlining.  The best long-term solution is to change the exception
representation and commit to either requiring or not requiring the more
complex edge-splitting logic;  this is just a shorter-term hack.

Jakob Stoklund Olesen 68d6d8ab87 Move TableGen's register bank classes to their own source file. 
I'll be moving some more code there to gather all of the
register-specific stuff in one place. Currently it is shared between
CodeGenTarget and RegisterInfoEmitter.

The plan is that CodeGenRegisters can compute the full register bank
structure while RegisterInfoEmitter only will handle the printing part.

Hans Wennborg de2e67e546 Handle overloaded operators in ?: precedence warning 
This is a follow-up to r132565, and should address the rest of PR9969:

Warn about cases such as

int foo(A a, bool b) {
 return a + b ? 1 : 2; // user probably meant a + (b ? 1 : 2);
}

also when + is an overloaded operator call.

Jakob Stoklund Olesen 5750ca7089 Remove custom allocation order boilerplate that is no longer needed. 
The register allocators automatically filter out reserved registers and
place the callee saved registers last in the allocation order, so custom
methods are no longer necessary just for that.

Some targets still use custom allocation orders:

ARM/Thumb: The high registers are removed from GPR in thumb mode. The
NEON allocation orders prefer to use non-VFP2 registers first.

X86: The GR8 classes omit AH-DH in x86-64 mode to avoid REX trouble.

SystemZ: Some of the allocation orders are omitting R12 aliases without
explanation. I don't understand this target well enough to fix that. It
looks like all the boilerplate could be removed by reserving the right
registers.

Cameron Zwarich 77a699a829 Fix PR10104 by adding a bounds check on a vector element access check. It was

the float member of { <2 x float>, float } as the 3rd element of the first
member.

Cameron Zwarich c3b1cc9aca Fix an assymmetry between ConvertScalar_ExtractValue and ConvertScalar_InsertValue. The 
former was using the size of the entire alloca, whereas the latter was correctly using
the allocated size of the immediate type being converted (which may differ from the size
of the alloca). This fixes PR10082.
