llvm/CMakeLists.txt: Fix LLVM_LIT_TOOLS_DIR since r143728. Cygwin does not need optional tools dir. MSVC and mingw may need one.

Forgot to commit the Header files. 
Rename generateUnknownVal -> makeGenericVal.

llvm-svn: 146337

Fix a bug in SimpleSValBuilder, where we should swap lhs and rhs when calling generateUnknownVal(), - the function which creates symbolic expressions when data is tainted. The issue is not visible when we only create the expressions for taint since all expressions are commutative from taint perspective.

Refactor SymExpr::symbol_iterator::expand() to use a switch instead of a chain of ifs.

<rdar://problem/10561406>

Stopped the SymbolFileDWARF::FindFunctions (...) from always calculating
the line table entry for all functions that were found. This can slow down
the expression parser if it ends up finding a bunch of matches. Fixed the 
places that were relying on the line table entry being filled in.

Discovered a recursive stack blowout that happened when "main" didn't have
line info for it and there was no line information for "main"

in CMake a bit more handy. Previously we would get such charming
versions as the following for revision NNNN and commit-ish XXXXX:
  3.1svnsvn-rNNNN
  3.1svngit-svn-rNNNN
  3.1svngit-svn-XXXXX

The mechanism selecting betwene the latter two was particularly odd, and
didn't work with all of the ways git-svn repos are set up apparently. It
also misses an important point -- both the revision *and* the git commit
might be relevant when working on a local branch some distance from
mainline. The new logic does several things:

1) It strips the redundant initial 'svn'.
2) It always looks for a git-svn revision number base, and when found
   includes it in the version.
3) If the git commit-ish for the current HEAD is not exactly that
   revision number, it is also included.

The resulting strings should roughly be:
  3.1svn-rNNNN
  3.1git-svn-rNNNN
  3.1git-svn-rNNNN-XXXXX

Suggestions on formatting etc always welcome. =] I've only looked at the
LLVM version string here, not Clang's (yet).

Note that the commit-ish reported is *not* terribly accurate. It updates
when 'cmake' is run, not when the binary is built. Still, it may be
better than nothing, especially if people have fairly long-lived git
repos and branches. This is not a new limitation, just didn't want
anyone to be surprised.

Make CR spill and restore use a reserved register. These operations cannot use the register scavenger because the scavenger can only scavenge one register and frame-index elimination may have already grabbed it.

- Even if a frame isn't present, we always try
  to use FindGlobalVariable to find variables.
  Instead of using frame->TrackGlobalVariable()
  to promote the VariableSP into a ValueObject,
  we now simply use ValueObjectVariable.

- When requesting the value of a variable, we
  allow returning of the "live version" of the
  variable -- that is, the variable in the
  target instead of a pointer to its freeze
  dried version in LLDB -- even if there is no
  process present.

The split point is picked such that the newly created water has the same
alignment as the function. This makes the island suitable for constant
pool entries with potentially higher alignment.

This also fixes an issue where the basic block was split one instruction
too late, causing nonconvergence of the algorithm.

There is still an issue with correctly packing differently aligned
entries in the island.
