This should fix PR10772.

Support an extension of ARM asm syntax to allow immediate operands to ADR instructions.  This is helpful for disassembler testing, and indeed exposed a disassembler bug that is also fixed here.

temporary was being passed as potentially-aliased memory.

Fix PR10755 by checking for invalid predicate codes from UNPREDICTABLE t2IT instructions when decoding their successors.
This is the last disassembly crash detected by exhaustive Thumb2 instruction space.  Major thanks to Chandler Carruth for making this kind of exhaustive testing possible.

Fixes an oversight, and adds verification to catch it in the unloop.ll tests.

I don't really like the patterns, but I'm having trouble coming up with a
better way to handle them.

I plan on making other targets use the same legalization
ARM-without-memory-barriers is using... it's not especially efficient, but
if anyone cares, it's not that hard to fix for a given target if there's
some better lowering.

- Allow undefined behavior interfering with undefined behavior.
- Add address space checks.

SimplifyCFG: If we have a PHI node that can evaluate to NULL and do a load or store to the address returned by the PHI node then we can consider this incoming value as dead and remove the edge pointing there, unless there are instructions that can affect control flow executed in between.

In theory this could be extended to other instructions, eg. division by zero, but it's likely that it will "miscompile" some code because people depend on div by zero not trapping. NULL pointer dereference usually leads to a crash so we should be on the safe side.

This shrinks the size of a Release clang by 16k on x86_64.

Also convert stack-addr-ps.cpp to use the analyzer instead of just Sema, now
that it doesn't crash, and extract the stack-block test into another file since
it errors, and that prevents the analyzer from running.

built locally from the source tree.  This is distinguished from self.lldbExec, which
can be used by test/benchmarks to measure the performances against other debuggers.

You can use environment variable LLDB_EXEC to specify self.lldbExec to the dotest.py
test driver, otherwise it is going to be populated with self.lldbHere.

Modify the regular tests under test dir, i.e., not test/benchmarks, to use self.lldbHere.
Also modify the benchmarks tests to use self.lldbHere when it needs an 'lldb' executable
with debug info to do the performance measurements.

scheme, return 'true' so that it doesn't try to run the old EH scheme's fixup on
the new code.

llvm-svn: 138605

This upgrade suffers from the problems of the old EH scheme - i.e., that the
calls to llvm.eh.exception() and llvm.eh.selector() can wander off and get
lost. It makes a valiant effort to reclaim these little lost lambs.

This is a first draft, so it hasn't yet been hooked up to the parser.

Much to everyone's surprise, the default constructor for TypeResult produces
an instance with Invalid == false. This seems like a decision we may want to
revisit.

emit call results into potentially aliased slots.  This allows us
to properly mark indirect return slots as noalias, at the cost
of requiring an extra memcpy when assigning an aggregate call
result into a l-value.  It also brings us into compliance with
the x86-64 ABI.
