If no destination label is available, just point to the node itself
instead of pointing to some source label. Source and destination labels are
not related in any way.

Graphviz can layout the graphs better if a node does not contain source
ports. Therefore only print the ports if the source ports are useful,
that means are not labeled with the empty string "".
This patch also simplifies graphs without any edgeSourceLabels e.g. the
dominance trees.

clang-cc: Add code (currently disabled) for parsing arguments using clang -cc1 functionality instead of LLVM's CommandLine.
 - It works and passes test suite, but I want to polish and test a wee bit more before making the switch.

Add CodeGenOptions::{SoftFloat,FloatABI}, and update the all the (far too many) places to use this instead of using the backend -soft-float and -float-abi= options.

Add TextDiagnosticBuffer::FlushDiagnostics, for forwarding the buffered diagnostics to a different diagnostics engine.

Don't try to generate common globals for C++ files, instead of depending on the FE to set NoCommon, and simplify CodeGenOptions initialization.

Put CompilerInvocation testing code in clang-cc instead of clang for now, I can't bear to link all of clang into 'clang' yet. :)
 - Still triggered by a magic leading -cc1 argument, as before.

stat a file but where mmaping it fails.  In this case, we emit an
error like:
t.c:1:10: fatal error: error opening file '../../foo.h'

instead of "cannot find file".

more. Update the syntax we're checking for and filecheckize it too.

This will fix the selfhost buildbots but will 'break' the others (sigh) because
they're still linked against older LLVM which is emitting less optimized IR.

was being added to the Result vector, but not being put in the
cache.  This means that if the cache was reused wholesale for a
later query that it would be missing this entry and we'd do an
incorrect load elimination.

Unfortunately, it's not really possible to write a useful 
testcase for this, but this unbreaks 255.vortex.

 - Clients that care about having the diagnostics output honor the user-controllable diagnostic options can buffer the diagnostics and issue them later.
