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.

- 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.

does. The _GLOBAL_OFFSET_TABLE_ is still magical in that we get a R_386_GOTPC,
but it doesn't change the immediate in the same way as when the expression
has no right hand side symbol.

An assertion was firing when parsing types due to trying to complete parent
class decl contenxt types too often.
Also, relax where "dsymutil" binary can come from in the Makefile.rules.

and StackID when asked for it.

Since we're not rewriting IVs in other loops, there's not much reason
to consider their stride when generating formulae.
This should reduce the number of useless formulas considered by LSR.

template instantiation), and that expression might produce a
temporary, invoke MaybeBindToTemporary. Otherwise, we forget to
destroy objects, release objects, etc. Fixes <rdar://problem/10531073>.

whether an expression is a (core) constant expression as a side-effect of
evaluation. This takes us from accepting far too few expressions as ICEs to
accepting slightly too many -- fixes for the remaining cases are coming next.
The diagnostics produced when an expression is found to be non-constant are
currently quite poor (with generic wording but reasonable source locations),
and will be improved in subsequent commits.

Backwards compatibility with 'gas'. #imm is the preferered and documented
syntax, but lots of existing code uses the '$' prefix, so we should
support it if we can.
