Hal Finkel b58ce85ecc Add -mqpx and -mno-qpx feature flags to toggle use of the PPC QPX vector instruction set 
I've renamed the altivec test to ppc-features (because now there is more than one feature to test).

Bill Schmidt eb03ae268e Fix PR14881 by implementing conversion rules between int and complex int. 
Prior to the patch, Clang does not properly promote types when a complex
integer operand is combined with an integer via a binary operator, or when
one is assigned to the other in either order.  This patch detects when
promotion is needed (and permissible) and generates the necessary code.

The test assmes no target has the same size operands for "char" and
"long long," and that no target performs arithmetic on char operands without
extending them to a larger format first.  If there are any targets for
which this is not the case, they should be XFAILed.

Benjamin Kramer c05aa958b1 InstSimplify: stripAndComputeConstantOffsets can be called with vectors of pointers too. 
Prepare it for vectors of pointers and handle simple cases. We don't handle
complicated cases because accumulateConstantOffset bails on pointer vectors.

Manuel Klimek 191c093af1 Re-design the convenience interfaces on MatchFinder. 
First, this implements a match() method on MatchFinder; this allows us
to get rid of the findAll implementation, as findAll is really a special
case of recursive matchers on match.

Instead of findAll, provide a convenience function match() that lets
users iterate easily over the results instead of needing to implement
callbacks.

Tim Northover e3d4236402 Add explicit triples to AArch64 tests 
Only Linux is supported at the moment, and other platforms quickly fault. As a
result these tests would fail on non-Linux hosts. It may be worth making the
tests more generic again as more platforms are supported.

Daniel Jasper 4b866274c3 Revamp of the basic layouting algorithm in clang-format. 
In order to end up with good solutions, clang-format needs to try
"all" combinations of line breaks, evaluate them and select the
best one. Before, we have done this using a DFS with memoization
and cut-off conditions. However, this approach is very limited
as shown by the huge static initializer in the attachment of
llvm.org/PR14959.

Instead, this new implementation uses a variant of Dijkstra's
algorithm to do a prioritized BFS over the solution space.

Some numbers:
lib/Format/TokenAnnotator.cpp: 1.5s -> 0.15s
Attachment of PR14959: 10min+ (didn't finish) -> 10s

No functional changes intended.

Michael J. Spencer 08b49bf27e [ELF][x86-64] Fix ifunc and add test. 
In an previous commit I managed to completely disable the IRELATIVE relocation
writing code. I also used the wrong addend for the static relocation. Fix both
these issues and add a test. This test is quite brittle because there's no way
to do arithmetic on variables in FileCheck.
