f1fa4fd282 128-bit sign extension and vector shift cleanups, contributed by Ken Werner 
(IBM).

9b2420d2b2 Initialize ShufBytes, as gcc 4.4 can't detect that the entire array is 
initialized and a warning about a potentially unintialized variable is
generated.

23132b188b prune the #includes in raw_ostream.h by moving a 
member out of line. ftostr is not particularly speedy,
so that method is presumably not perf sensitive.

a60e51f7e8 Make linkerprivate work for ARM and PPC. Testcase covers 
all Darwin targets; could be split into separate tests for
the chip subdirectories, but from Chris' last mail on testing
I assume he'd rather have only one test.  Generic seems to be
the best available, maybe there should be a Darwin subdirectory?

eb01abaad1 Implement support for ISRs. 
Clone functions that are shared between the Main thread and Interrupt thread.
CallSites are changed in AsmPrinter currently. A better solution would have been to modify the legalizer (SoftenFloat) to allow targets to change the name of libcalls for float operations. But that currently breaks other targets.
Also, cloing of automatic variables is done AsmPrinter, a better approach would
be to use the ValueMap in CloneFunction itself.

5cfd4ddece PowerPC inline asm was emitting two output operands 
for a single "m" constraint; this is wrong because the
opcode of a load or store would have to change in parallel.
This patch makes it always compute addresses into a register,
which is correct but not as efficient as possible.  7144566.

3f5bb168bc An overhaul of the exception handling code. This is arguably more correct than 
what was there before. In "no FP mode", we weren't generating labels and unwind
table entries after each "push" instruction. While more than likely "okay", it's
not technically correct. The major thing was that the ordering of when to define
a new CFA register and at what offset wasn't correct. This would cause the
exception handling to fail in ways most miserable to users.

I also cleaned up some code a bit. There's one function which has a "return" at
the beginning, so it's never used. Should I just remove it? :-)
