It's not really a "ScopeDIE", as such - it's the abstract function

Rafael correctly pointed out that the restriction is unnecessary. Although the
tests are intended to ensure that we dont abort due to an assertion, running the
tests in all modes is better since it also ensures that we dont crash without
assertions. Always run these tests to ensure that we can handle invalid input
correctly.

and sharing it with all of its FuncUnwinders, have each FuncUnwinder
create an AssemblyProfiler on demand as needed. I was worried that
the cost of creating the llvm disassemblers would be high for this
approach but it's not supposed to be an expensive operation, and it
means we don't need to add locks around this section of code.

The last step of _mm_cvtps_pi16 should use _mm_packs_pi32, which is a function

values.

to its unwind assembly profiler to all of the FuncUnwinders (one
per symbol) under it. If lldb is running multiple targets, you
could get two different FuncUnwinders in the same Module trying
to use the same llvm disassembler simultaneously and that may be
a re-entrancy problem.
Instead, the UnwindTable has the unwind assembly profiler and when
the FuncUnwinders want to use it, they get exclusive access to
the assembly profiler until they're done using it.

ScalarEvolution::isKnownPredicate() can wrongly reduce a comparison
when both the LHS and RHS are SCEVAddRecExprs. This checks that both
LHS and RHS are guarded in the case when both are SCEVAddRecExprs.
The test case is against indvars because I could not find a way to
directly test SCEV.

/alternatename is a command line option to define a weak alias. You
can use it as /alternatename:foo=bar to define "foo" as a weak alias
for "bar".
Because it's a command line option, the weak alias mapping is in the
LinkingContext object, and not in a object file being read.
Previously, we looked up the mapping each time we read a new symbol
from a file, to check if there is a weak alias defined for the symbol.
That's not wrong, but had made function signature's a bit complicated --
we had to pass the mapping object to many functions. Now their
parameter lists are much cleaner.
This also has another (unrealized) benefit. parseFile() now read a
file and then add alias symbols to the file. In the first pass a
LinkingContext object is not used at all. That should make it easy
to read files from archive files speculatively, as the first pass
is free from side effect.

This was fairly broken. For example,
@__dso_handle would or would not get an unnamed_addr depending on how many
global destructors were used in a translation unit.
The consensus was that not every runtime variable is unnamed_addr and that
__dso_handle handle should not be, so just don't add unnamed_addr in
CreateRuntimeVariable.

Windows can't handle paths longer than 260 code points without \\?\. Even
with \\?\ it can't handle path components longer than 255 code points. So
limit graph names to the arbitrary length of 140. Random characters are still
added to the end, so it's ok if graph names collide.

i386.
This fixes two more MCJIT regression tests on i386:
ExecutionEngine/MCJIT/2003-05-06-LivenessClobber.ll
ExecutionEngine/MCJIT/2013-04-04-RelocAddend.ll
The implementation of processScatteredVANILLA is tasteless (*ba-dum-ching*),
but I'm working on a substantial tidy-up of RuntimeDyldMachO that should
improve things.
This patch also fixes a type-o in RuntimeDyldMachO::processSECTDIFFRelocation,
and teaches that method to skip over the PAIR reloc following the SECTDIFF.

Summary:
The limits on the number of fix-it hints and ranges attached to a
diagnostic are arbitrary and don't apply universally to all users of the
DiagnosticsEngine. The way the limits are enforced may lead to diagnostics
generating invalid sets of fixes. I suggest removing the limits, which will also
simplify the implementation.

This patch moves the handling of -pass-remarks* over to

This patch teaches the x86 backend how to efficiently lower ISD::BITCAST dag
nodes from MVT::f64 to MVT::v4i16 (and vice versa), and from MVT::f64 to
MVT::v8i8 (and vice versa).
This patch extends the logic from revision 208107 to also handle MVT::v4i16
and MVT::v8i8. Also, this patch correctly propagates Undef values when
performing the widening of a vector (example: when widening from v2i32 to
v4i32, the upper 64bits of the resulting vector are 'undef').
