Basically, if you have a function that's inlined into the caller, it may not
have any 'call' instructions, but any 'resume' instructions it may have should
still be forwarded to the outer (caller's) landing pad. This requires that all

Implement builtin_{setjmp/longjmp} on PPC

__builtin_{setjmp/longjmp} functional on PPC platforms. The implementation
strategy is similar to that on X86, with the exception that a branch-and-link
variant is used to get the right jump address. Credit goes to Bill Schmidt for
suggesting the use of the unconditional bcl form (instead of the regular bl
instruction) to limit return-address-cache pollution.
Benchmarking the speed at -O3 of:
static jmp_buf env_sigill;
void foo() {
__builtin_longjmp(env_sigill,1);

for (int i = 0; i < c; ++i) {
if (__builtin_setjmp(env_sigill)) {
goto done;
} else {
foo();

vs. the same code using the libc setjmp/longjmp functions on a P7 shows that
this builtin implementation is ~4x faster with Altivec enabled and ~7.25x
faster with Altivec disabled. This comparison is somewhat unfair because the

[SROA] Prefix names using a custom IRBuilder inserter.
The key part of this is ensuring that name prefixes remain in a Twine
form until we get to a point where we can nuke them under NDEBUG. This
is tricky using the old APIs as they played fast and loose with Twine,
which is prone to serious error. The inserter is much cleaner as it is
actually in the call stack leading to the setName call, and so has
a good opportunity to prepend the prefix.
This matters more than you might imagine because most runs over an
alloca find a single partition, and rewrite 3 or 4 instructions
referring to it. As a consequence doing this lazily and exclusively with
Twine allows the optimizer to delete more of it and shaves another 2% to
3% off of the release build's SROA run time for PR15412. I also think
the APIs are cleaner, and the use of Twine is more reliable, so

Move library call prototype attribute inference to functionattrs
The simplify-libcalls pass implemented a doInitialization hook to infer
function prototype attributes for well-known functions. Given that the
simplify-libcalls pass is going away *and* that the functionattrs pass
is already in place to deduce function attributes, I am moving this logic
to the functionattrs pass. This approach was discussed during patch
review:

Per discussion on cxx-abi-dev, switch from comparing type_info objects to

Split ubsan runtime into three pieces (compiler-rt part):
* libclang_rt-san-* is sanitizer_common, and is linked in only if no other
sanitizer runtime is present.
* libclang_rt-ubsan-* is the piece of the runtime which doesn't depend on
a C++ ABI library, and is always linked in.
* libclang_rt-ubsan_cxx-* is the piece of the runtime which depends on a
C++ ABI library, and is only linked in when linking a C++ binary.
The Darwin ubsan runtime is unchanged.

This change also switches us to using -whole-archive for the ubsan runtime
(which is made possible by the above split), and switches us to only linking
the sanitizer runtime into the main binary and not into DSOs (which is made
possible by using -whole-archive).
The motivation for this is to only link a single copy of sanitizer_common
into any binary. This is becoming important now because we want to share
more state between multiple sanitizers in the same process (for instance,
we want a single shared output mutex).
The Darwin ubsan runtime is unchanged; because we use a DSO there, we don't
need this complexity.
