Also, eliminate global 'IsReferenceBuild' in SATestBuild. It doesn't get

IntegersSubset devided into IntegersSubsetGeneric and into IntegersSubset itself. The first has no references to ConstantInt and works with IntItem only.
IntegersSubsetMapping also made generic. Here added second template parameter "IntegersSubsetTy" that allows to use on of two IntegersSubset types described below.

IntItem cleanup. IntItemBase, IntItemConstantIntImp and IntItem merged into IntItem. All arithmetic operators was propogated from APInt. Also added comparison operators <,>,<=,>=. Currently you will find set of macros that propogates operators from APInt to IntItem in the beginning of IntegerSubset. Note that THESE MACROS WILL REMOVED after all passes will case-ranges compatible. Also note that these macros much smaller pain that something like this:
if (V->getValue().ugt(AnotherV->getValue()) { ... }

These changes made IntItem full featured integer object. It allows to make IntegerSubset class generic (move out all ConstantInt references inside and add unit-tests) in next commits.

Stub files for common symbolizer for AddressSanitizer and ThreadSanitizer tools.
It is an analogue of addr2line utility and should allow to map instruction address to a location
in source code at run-time. It should use debug information (in DWARF) in a binary, and hopefully
it would be possible to re-use code from llvm/DebugInfo/DIContext.h

Remove fadd(fmul) patterns for FMA3. This needs to be implemented by paying attention to FP_CONTRACT and matching @llvm.fma which is not available yet. This will allow us to enablle intrinsic use at least though.

with some trivial casts between the call and return (i.e. because the

We handle struct byval by inserting a pseudo op, which will be expanded to a
loop at ExpandISelPseudos.
A separate patch for clang will be submitted to enable struct byval.

When the Platform launches a process for debugging, make sure it goes into a separate process group, otherwise ^C will both cause us to try to Stop it manually, AND send it a SIGINT, which can confuse us.

If the Driver's input reader gets an Interrupt and the current command line is empty, then treat that interrupt as an instruction to Stop the process of the currently selected target.

the confusion among all of the uses of Best* in relation to the set of
possible typo correction results. Also add a method to return the set of
typo corrections that have the single best edit distance--it returns the
second half of the first pair in TypoEditDistanceMap (with
getBestEditDistance already returning the first half).

 - compute size & offset at the same time. The side-effects of this are that we now support negative GEPs. It's now approaching a phase that it can be reused by other passes (e.g., lowering of the objectsize intrinsic)
 - use APInt throughout to handle wrap-arounds
 - add support for PHI instrumentation
 - add a cache (required for recursive PHIs anyway)
 - remove hoisting support for now, since it was wrong in a few cases

sorry for the churn here.. tests will follow soon.
