inject some code in that will run via the "__mod_init_func" method that
registers the gcov "writeout" function to execute at exit time.

The problem is that the "__mod_term_func" method of specifying d'tors is
deprecated on Darwin. And it can lead to some ambiguities when dealing with
multiple libraries.

After physreg coalescing was disabled, these functions can't do anything
useful with physregs anyway.

MCRegAliasIterator can include Reg itself in the list.

Need to figure out how to get Frontend's warning parsing without bringing

This removes a bit of context from the verifier erros, but reduces code
duplication in a fairly critical part of LLVM and makes dominates easier to test.

show-enabled uses the command line you give it to build a CompilerInstance,
so any flags you pass will be processed as if running clang proper.

MCRegAliasIterator can optionally visit the register itself, allowing
for simpler code.

Fixed an issue with the current type being set to DIE_IS_BEING_PARSED in the m_die_to_type map by making sure the type pointer is valid.

Added the ability to disassembly GDB remote packets with the python file. This will make it easier to symbolicate the packet log output since we can use the lldb.utils.symbolication package module to symbolicate register values.

This patch will optimize the following:
  sub r1, r3
  cmp r3, r1 or cmp r1, r3
  bge L1
TO
  sub r1, r3
  bge L1 or ble L1

If the branch instruction can use flag from "sub", then we can eliminate
the "cmp" instruction.

BoundsChecking: fix a bug when the handling of recursive PHIs failed and could leave dangling references in the cache
add regression tests for this problem.

This implements codegen support for accesses to thread-local variables
using the local-dynamic model, and adds a clean-up pass so that the base
address for the TLS block can be re-used between local-dynamic access on
an execution path.

Also, re-use glob results when looking for failure logs.

Also, eliminate global 'IsReferenceBuild' in SATestBuild. It doesn't get
passed around that much.

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
