recent change to make SEL a builtin type (fixes radar 7425510).

for all the processors where I have tried it, and even when it might not help
performance, the cost is quite low.  The opportunities for duplicating
indirect branches are limited by other factors so code size does not change
much due to tail duplicating indirect branches aggressively.

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.

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".

divide/remainder since these operations can trap by unroll them and adding undefs
