This allows SCEVExpander to run on the IV expressions.
This codifies an assumption made by LSR to complete the fix for
PR11356, but I haven't been able to generate a separate unit test for
this part. I'm adding it as an extra safety check.

intrinsics with target-indepdent intrinsics. The first instruction(s) to be
handled are the vector versions of count leading zeros (ctlz).
The changes here are to clang so that it generates a target independent
vector ctlz when it sees an ARM dependent vector ctlz. The changes in llvm
are to match the target independent vector ctlz and in VMCore/AutoUpgrade.cpp
to update any existing bc files containing ARM dependent vector ctlzs with
target-independent ctlzs. There are also changes to an existing test case in
llvm for ARM vector count instructions and a new test for the bitcode upgrade.

There is deliberately no test for the change to clang, as so far as I know, no
consensus has been reached regarding how to test neon instructions in clang;

current symbol context is a C++ or Objective-C
instance method.
Specifically, ensure that we fetch information
on the current block, not just the current
function.

removes the largest scaling problem in the test cases from PR13225 when
ASan is switched to insert basic blocks in the natural CFG order.
It may also solve some scaling problems for more normal code with large
numbers of basic blocks and variables.

Call instructions are no longer required to be variadic, and
variable_ops should only be used for instructions that encode a variable
number of arguments, like the ARM stm/ldm instructions.

Function argument registers are added to the call SDNode, but
InstrEmitter now knows how to make those operands implicit, and the call
instruction doesn't have to be variadic.
Explicit register operands should only be those that are encoded in the
instruction, implicit register operands are for extra dependencies like
call argument and return values.

is used in cases where global symbols are
directly represented in the GOT and we use an
offset into the global offset table.
This patch adds direct object support for R_MIPS_GOT_DISP.

I did not take into account, that this patch fails to compile without the
llvm.codegen patch applied. This breaks buildbots.
I revert this until we found a solution to commit this without buildbots
complaining.
This reverts commit cb43ab80e94434e780a66be3b9a6ad466822fe33.

Translate the selected parallel loop body into a ptx string and run it
with cuda driver API. We limit this preliminary implementation to
target the following special test cases:
- Support only 2-dimensional parallel loops with or without only one
innermost non-parallel loop.
- Support write memory access to only one array in a SCoP.

to the same signature. Fix a bug in the type printer which would cause this
diagnostic to print wonderful types like 'const const int *'.

Also made the symbolication of the crash logs more efficient when using the "--crashed-only" ("-c") option where only the crashed thread is symbolicated. We now only download the images for the frames in the crashed thread.
