Evan Cheng 45d8f8a08c Do not fold ADD / SUB into load / store (to form pre-indexed, post-indexed 
load / store) if the ADD / SUB has a live definition of CPSR.

Bug reported by David Meyer. Alas, no test case.

Kaelyn Uhrain 1c75d4084d Remove the unused TypoCorrectionConsumer::MaxEditDistance. 
MaxEditDistance was effectively unused as it being initialized to the max
unsigned valued but never updated. Removing it avoids conversion
headaches once the "edit distance" of a typo correction is a weighted
composite of several values instead of roughly the number of characters
changed; comparing the weighted composite value to the number of
characters in a typo would require some form of normalization to make it
comparable to the old, character-based notion of edit distance.

Bill Wendling 3ae7dd377d Reserve space in these vectors to prevent having to grow the array too 
much. This gets us an addition 0.9% on 445.gobmk.

Bob Wilson 7ecbd32e4e Filter a few more options not recognized by gcc. <rdar://problem/10814020> 
These are new options that gcc doesn't recognize so the clang driver needs
to remove them when it falls back to invoking gcc.

Bill Wendling 9972958a89 Use a more efficient container for these values. Also reserve space when using a 
std::vector.

Andrew Trick 5470205ad2 This is a small patch with a couple of improvements for running lit with --debug: 
1. Added a status note when a config file is loaded directly with load_config. This helps notice loads of lit.cfg from lit.site.cfg
2. Added a status note on the result of a config load. Previously, it was just notifying that it tries to load a config file. Now it will also say whether the load succeeded or the file wasn't found

The two changes give better visibility into which config files were actually loaded by lit. The effect is only on --debug runs.

Patch by Eli Bendersky!

Kostya Serebryany 9e0d377400 The patch resolves the conflict between AddressSanitizer and load widening (GVN). 
The problem initially reported by Mozilla folks (http://code.google.com/p/address-sanitizer/issues/detail?id=20),
but it also prevents us from enabling LLVM bootstrap with AddressSanitizer.

Abramo Bagnara e0a70b2656 Added source location for the template keyword in DependentTemplateSpecializationTypeLoc nodes (DTSTLoc). 
The new info is propagated to TSTLoc on template instantiation, getting rid of 3 FIXMEs in TreeTransform.h and another one Parser.cpp.

Simplified code in TypeSpecLocFiller visitor methods for DTSTLoc and DependentNameTypeLoc by removing what now seems to be dead code (adding corresponding assertions).

Jakob Stoklund Olesen 769de20ae9 Remove some unused functions. 
LiveIntervalAnalysis has a number of functions that simply forward to
SlotIndexes.  Since SlotIndexes is a stand-alone analysis now, clients
should really refer to it directly.
