doesn't return a result.  If that expression can't
be run in the current context (for example, if it
uses a function and there is no running process)
then we used to try to destroy the nonexistent
result variable.  We now only destroy the result
variable if we actually made one.

MachineInstr sequence.

This uses the new target interface for tracking register pressure
using pressure sets to model overlapping register classes and
subregisters.

RegisterPressure results can be tracked incrementally or stored at
region boundaries. Global register pressure can be deduced from local
RegisterPressure results if desired.

This is an early, somewhat untested implementation. I'm working on
testing it within the context of a register pressure reducing
MachineScheduler.

Instead of -polly-run-import-jscop and -polly-run-export-jscop, we just use
-polly-import and -polly-export.

We now support -polly-optimizer=isl, -polly-optimizer=pocc and
-polly-optimizer=none. The option -polly-no-optimizer is gone.

this pattern new users are added to the load node, which prevent the selection
of the blend pattern. This commit provides fallback patterns which perform
in-vector broadcast (using in-vector vbroadcast in AVX2 and pshufd on AVX1).

Look for the 'Is Simulated' module flag. This indicates that the program is compiled to run on a simulator.

Removing the @expectedFailurei386 decorator from test cases that now work as a result of the latest changes to Value.cpp

llvm-svn: 155419

This patch fixes a bug where LLDB was incorrectly setting the address-size on a DataExtractor to be sizeof(void*) when the ValueObject came out of the expression parser
This worked correctly for 64-bit targets, but broke down data formatters in i386 mode. The formatters would try to read pointers out of the frozen-dried objects,
but were unable to do so because they would try fetching 8 bytes from a DataExtractor with only 4 bytes in it. This patch fixes the issue by always making the pointer-size
for a DataExtractor match the target setting.

Fixed an issue where we get NULL compile units back from the symbol vendor. We need symbol vendors to be able to quickly give an estimate of the compile units that they have without having to fully vette them first, so anyone getting compile units from a module should be able to deal with a NULL compile unit being returned for a given index.
