This reverts r295564. I missed that clang was still using the intrinsics despite our half implemented autoupgrade support.

It seems we were already upgrading 128-bit VPCMOV, but the intrinsic was still defined and being used in isel patterns. While I was here I also simplified the tablegen multiclasses.

Several visitors check if operands to the instruction are constants,
either as it is or after looking up SimplifiedValues, check if the
result is a constant and update the SimplifiedValues map. This
refactoring splits it into a common function that does the checking of
whether the operands are constants and updating of the SimplifiedValues
table, and an instruction specific part that is implemented by each
instruction visitor as a lambda and passed to the common function.

Syntax highlighting has been done line-at-a-time. Done this way, the lexer
resets the context at each line, distorting the formatting.
This change will render the whole file at once and feed the highlighted text
line-at-a-time to be wrapped by the SourceFileRenderer.
Leading/trailing newlines were being ignored by Pygments but since each line
was rendered in its own row, it didn't matter. This bug was masked by the
line-at-a-time algorithm. So now we need to add "stripnl=False" to the
CppLexer to change its behavior to match the expectation.

Before this patch we happened to visit twice, one when scanning
MDNodes and the other one while visiting the function. Remove
the explicit call to visitDISubprogram there, so we don't emit
the same error twice in case the verifier fail and we save some
time when running it.
Thanks to Justin Bogner for the report and Adrian for the quick
review!

This avoids creating a DILocation just to represent a line number,
since creating Metadata is expensive. Creating a DiagnosticLocation
directly is much cheaper.

This is still breaking builds because some compilers think
this type is not trivially copyable even when it should be.
Reverting this static_assert until I have time to investigate.

In an effort to generalize this so it can be used by more than
just PDB code, we shouldn't assume little endian.

This creates and uses a DiagnosticLocation type rather than using
DebugLoc for this purpose in the backend diagnostics. This is NFC for
now, but will allow us to create locations for diagnostics without
having to create new metadata nodes when we don't have a DILocation.

- Adapt MachineBasicBlock::getName() to have the same behavior as the IR
BasicBlock (Value::getName()).
- Add it to lib/CodeGen/CodeGen.cpp::initializeCodeGen so that it is linked in
the CodeGen library.
- MachineRegionInfoPass's name conflicts with RegionInfoPass's name ("region").
- MachineRegionInfo should depend on MachineDominatorTree,
MachinePostDominatorTree and MachineDominanceFrontier instead of their
respective IR versions.
- Since there were no tests for this, add a X86 MIR test.

A line number doesn't make much sense if you don't say where it's
from. Add a verifier check for this and update some tests that had
bogus debug info.

Newer ppc supports unaligned memory access, it reduces the cost of unaligned memory access significantly. This patch handles this case in PPCTTIImpl::getMemoryOpCost.
This patch fixes pr31492.

This is resubmit of r292680, which was reverted by r293092. The internal application failures were actually caused by a source code bug.
