Jordan Rose a522f1cf8b Revert "[analyzer] Disable STL inlining. Blocked by PR13724."
While PR13724 is still an issue, it's not actually an issue in the STL.
We can keep this option around in case there turn out to be widespread
false positives due to poor modeling of the C++ standard library functions,
but for now we'd like to get more data.

This reverts r163633 / c6baadceec1d5148c20ee6c902a102233c547f62.

Dmitri Gribenko 9304d86329 Comment parsing: handle non-builtin commands correctly. After semantic
analysis registers a command, it becomes a "known" command for the lexer, since
it has an ID.  Having this freedom of choice to register a command is a good
thing since BriefParser does not need this.

But the parser should still invoke the correct semantic analysis method
(actOnUnknownCommand) in this case.

Jordan Rose e35fdeb330 [analyzer] Use the static type for a virtual call if the dynamic type is worse.
reinterpret_cast does not provide any of the usual type information that
static_cast or dynamic_cast provide -- only the new type. This can get us
in a situation where the dynamic type info for an object is actually a
superclass of the static type, which does not match what CodeGen does at all.
In these cases, just fall back to the static type as the best possible type
for devirtualization.

Should fix the crashes on our internal buildbot.

Manman Ren 571d9e4b80 SimplifyCFG: preserve branch-weight metadata when creating a new switch from
a pair of switch/branch where both depend on the value of the same variable and
the default case of the first switch/branch goes to the second switch/branch.

Code clean up and fixed a few issues:
1> handling the case where some cases of the 2nd switch are invalidated
2> correctly calculate the weight for the 2nd switch when it is a conditional eq

Testing case is modified from Alastair's original patch.

Jakob Stoklund Olesen d346d4871a Add TRI::getSubRegIndexLaneMask().
Sub-register lane masks are bitmasks that can be used to determine if
two sub-registers of a virtual register will overlap. For example, ARM's
ssub0 and ssub1 sub-register indices don't overlap each other, but both
overlap dsub0 and qsub0.

The lane masks will be accurate on most targets, but on targets that use
sub-register indexes in an irregular way, the masks may conservatively
report that two sub-register indices overlap when the eventually
allocated physregs don't.

Irregular register banks also mean that the bits in a lane mask can't be
mapped onto register units, but the concept is similar.

Jakob Stoklund Olesen dd40fda52d Clean the sub-reg index composition maps at emission.

Jakob Stoklund Olesen 21e2f1c6e5 Add MCRI::getNumSubRegIndices() and start checking SubRegIndex ranges.
Apparently, NumSubRegIndices was completely unused before. Adjust it by
one to include the null subreg index, just like getNumRegs() includes
the null register.

Tobias Grosser 6a2da6b9c8 Add test cases for multi-dimensional variable lengths arrays
At the moment we can handle such arrays only by conservatively assuming that
each access to such an array may touch any element in the array. It would be
great if we could improve Polly/LLVM at some point, such that we can
recover the multi-dimensionality of the accesses.

ObjectContainerBSDArchive::CreateInstance %z8.8x is not a valid printf arg specifier, %8.8zx would work
for size_t arg but this arg is addr_t.  use %8.8llx and cast up to uint64_t.

ObjectFile::FindPlugin ditto.
