i128). In that case, we may not be able to print out the MCExpr as an
expression. For instance, we could have an MCExpr like this:

    0xBEEF0000BEEF0000 | (0xBEEF0000BEEF0000 << 64)

The MCExpr printer handles sizes up to 64-bits, but this expression would
require 128-bits. In this situation, try to evaluate the constant expression and
emit that as the value into 64-bit chunks.

Remove code that prevented lowering shuffles if they are used by load and themselves used by a extract_vector_elt. This was done to allow the DAG combiner to collapse to a single element load. Unfortunately, sometimes the extract_vector_elt would disappear before DAG combine could do the transformation leaving a vector_shuffle that isel couldn't handle. New code lets the shuffle be converted to a target specific node, but then adds a combine routine that can convert target specific nodes back to vector_shuffles if the folding criteria are met.

Factor out target shuffle mask decoding from getShuffleScalarElt and use a SmallVector of int instead of unsigned for shuffle mask in decode functions. Preparation for another change.

When combining (vextract shuffle (load ), <1,u,u,u>), 0) -> (load ), add users of the final load to the worklist too. Needed by changes I'm preparing to make to X86 backend.

LLDB can match incorrect line table entries when an address is between two valid line entries (in the gap between the valid debug info), now it doesn't!

Added a fix to the crash log script that allows you to locate and load a binary from any location and _then_ do the symbolication. Something like:

(lldb) file /path/to/file.so
(lldb) crashlog crash.log
....

Then if the file.so has already been loaded it will use the one that is already in LLDB without trying to match up the paths.

code invariant. This will regress debug info for arguments where
we elide the alloca created.

to pass to the toolchain in order to build the inferior programs to be run/debugged
duirng the test suite.  The architecture might dictate some special CFLAGS which are
more easily specified in a central place (like the command line) instead of inside
make rules.

For Example,

./dotest.py -v -r /shared/phone -A armv7 -E "-isysroot your_sdk_root" functionalities/watchpoint/hello_watchpoint

will relocate the particular test directory ('functionalities/watchpoint/hello_watchpoint' in this case) to a
new directory named '/shared/phone'.  The particular incarnation of the architecture-compiler combination of the
test support files are therefore to be found under:

/shared/phone.arch=armv7-compiler=clang/functionalities/watchpoint/hello_watchpoint

The building of the inferior programs under testing is now working.

The actual launching/debugging of the inferior programs are not yet working,
neither is the setting of a watchpoint on the phone.

1) opt is not usually in the same path as the target program. Even for
the bugpoint as a standalone app, it should be more portable to search
in PATH, isn't it?
2) bugpoint driver accounts opt plugins, but does not list them in the
final output command.

Massive enumeration name changes: a number of enums in ValueObject were not following the naming pattern
Changes to synthetic children:
 - the update(self): function can now (optionally) return a value - if it returns boolean value True, ValueObjectSyntheticFilter will not clear its caches across stop-points
   this should allow better performance for Python-based synthetic children when one can be sure that the child ValueObjects have not changed
 - making a difference between a synthetic VO and a VO with a synthetic value: now a ValueObjectSyntheticFilter will not return itself as its own synthetic value, but will (correctly)
   claim to itself be synthetic
 - cleared up the internal synthetic children architecture to make a more consistent use of pointers and references instead of shared pointers when possible
 - major cleanup of unnecessary #include, data and functions in ValueObjectSyntheticFilter itself
 - removed the SyntheticValueType enum and replaced it with a plain boolean (to which it was equivalent in the first place)
Some clean ups to the summary generation code
Centralized the code that clears out user-visible strings and data in ValueObject
More efficient summaries for libc++ containers

Fixed a case where the source path remappings on the module were too expensive to
use when we try to verify (stat the file system) that the remapped path points to
a valid file. Now we will use the lldb_private::Module path remappings (if any) when
parsing the debug info without verifying that the paths exist so we don't slow down
line table parsing speeds.

I would really like to write the handlers in terms of C++11 atomics.  This would give us the best performance, portablity, and safety tradeoff.  Unfortunately I can not yet do that.  So I've put the desired code in comments, and reverted the handler getters to the slower but safer legacy atomic intrinsics.
