ARM: maintain BB ordering when expanding WIN__DBZCHK
It is possible to have a fallthrough MBB prior to MBB placement. The original
addition of the BB would result in reordering the BB as not preceding the
successor. Because of the fallthrough nature of the BB, we could end up
executing incorrect code or even a constant pool island! Insert the spliced BB

[sanitizer] Add memset, memmove, and memcpy to the common interceptors
Summary:
Currently, sanitizer_common_interceptors.inc has an implicit, undocumented
assumption that the sanitizer including it has previously declared
interceptors for memset and memmove. Since the memset, memmove, and memcpy
routines require interception by many sanitizers, we add them to the
set of common interceptions, both to address the undocumented assumption
and to speed future tool development. They are intercepted under a new
flag intercept_intrin.
The tsan interceptors are removed in favor of the new common versions. The
asan and msan interceptors for these are more complex (they incur extra
interception steps and their function bodies are exposed to the compiler)
so they opt out of the common versions and keep their own.

[ObjCXX] Warn undeclared identifiers.
Instantiation dependence were not being handled correctly for OpqaueValueExpr
AST nodes. As a result, if an undeclared identifier was used in a CXXNewExpr
that is assigned to a ObjC property, there would be no error during parsing, and
there would be a crash during code gen. This patch makes sure that an error
will be issued during parsing in this case.
Before the fix, if CXXNewExpr has a typo, its InstantiationDependent will be
set to true, but if it is wrapped in a OpaqueValueExpr, the OpaqueValueExpr will
not be instantiation dependent, causing the TypoExpr not be to resolved. The fix
propagates InstantiationDependent to OpaqueValueExpr from its SourceExpr. It

Bitcode: Collect all MDString records into a single blob
Optimize output of MDStrings in bitcode. This emits them in big blocks
(currently 1024) in a pair of records:
- BULK_STRING_SIZES: the sizes of the strings in the block, and
- BULK_STRING_DATA: a single blob, which is the concatenation of all
the strings.
Inspired by Mehdi's similar patch, http://reviews.llvm.org/D18342, this
should (a) slightly reduce bitcode size, since there is less record
overhead, and (b) greatly improve reading speed, since blobs are super
cheap to deserialize.
I needed to add support for blobs to streaming input to get the test
suite passing.
- StreamingMemoryObject::getPointer reads ahead and returns the
address of the blob.
- To avoid a possible reallocation of StreamingMemoryObject::Bytes,
BitstreamCursor::readRecord needs to move the call to JumpToEnd
forward so that getPointer is the last bitstream operation.

Fix DenseMap::reserve(): the formula was wrong
Summary:
Just running the loop in the unittests for a few more iterations
(till 48) exhibit that the condition on the limit was not handled
properly in r263522.
Rewrite the test to use a class to count move/copies that happens
when inserting into the map.
Also take the opportunity to refactor the logic to compute the
number of buckets required for a given number of entries in the map.
Use this when constructing a DenseMap with a desired size given to
the constructor (and add a tests for this).

Use Clang's FixItHints to correct expressions with "trivial" mistakes (e.g. "." for "->".)
This feature is controlled by an expression command option, a target property and the
SBExpressionOptions setting. FixIt's are only applied to UserExpressions, not UtilityFunctions,
those you have to get right when you make them.
This is just a first stage. At present the fixits are applied silently. The next step
is to tell the user about the applied fixit.

Bitcode: Stop using MODULE_CODE_METADATA_VALUES
The motivation for MODULE_CODE_METADATA_VALUES was to enable an
-flto=thin scheme where:
1. First, one function is cherry-picked from a bitcode file.
2. Later, another function is cherry-picked.
3. Later, ...
4. Finally, the metadata needed by all the previous functions is
loaded.
This was abandoned in favour of:
1. Calculate the superset of functions needed from a Module.
2. Link all functions at once.
Delayed metadata reading no longer serves a purpose. It also adds
a few complication, since we can't count on metadata being properly
parsed when exiting the BitcodeReader. After discussing with Teresa, we
agreed to remove it.
The code that depended on this was removed/updated in r264326.

IR: Stop upgrading !llvm.loop attachments via MDString

Add utility script to generate checks for opt or llc regression tests
This is an enhancement of the existing update_llc_test_checks.py script.
It adds some of the functionality from the script used in D17999 to make
the IR checking more flexible.
The bad news:
This actually is 'My First Python Program'. Thus, it's likely that I have
violated all best practices of Python programming if I've made a functional
change from the original program. If you see anything that's obviously
wrong, please let me know or feel free to fix it. I didn't even read any
documentation...
The good news:
I tested this on ~10 existing opt/llc regression tests, and it does what
I hoped for. It produces exact checking for IR regression tests and doesn't
signficantly change the existing llc-with-x86-target asm checking. The opt
tests that were modified in r263667, r263668, r263674, and r263679 are
examples of the expected results, except that this version of the script
puts the check lines ahead of the IR to follow the existing llc/asm
behavior.
If there are no complaints/fallout, we should be able to remove the
original script. Extending this script to be used for non-x86 and clang
regression tests would be the expected follow-up steps.
