Emit an error when using "target modules add PATH" where PATH points to a debug info only (dSYM) file.
Also added a "--uuid" option for "target modules add --uuid UUID" to locate and load a module by UUID if the host supports it.

Prevent async and sync calls to get profile data from stomping on each other.
At the same time, don't use '$' as end delimiter per chunk of profile data.

This revision attempts to recognize following population-count pattern:
while(a) { c++; ... ; a &= a - 1; ... },
where <c> and <a>could be used multiple times in the loop body.
TODO: On X8664 and ARM, __buildin_ctpop() are not expanded to a efficent
instruction sequence, which need to be improved in the following commits.
Reviewed by Nadav, really appreciate!

the last invoke instruction in the function. This also removes the last landing
pad in an function. This is fine, but with SjLj EH code, we've already placed a
bunch of code in the 'entry' block, which expects the landing pad to stick
around.
When we get to the situation where CGP has removed the last landing pad, go
ahead and nuke the SjLj instructions from the 'entry' block.

This patch migrates the puts optimizations from the simplify-libcalls
pass into the instcombine library call simplifier.
All the simplifiers from simplify-libcalls have now been migrated to
instcombine. Yay! Just a few other bits to migrate (prototype attribute
inference and a few statistics) and simplify-libcalls can finally be put
to rest.

MachOObjectFile owns a MachOObj, but never frees it. Both MachOObjectFile
and MachOObj want to own the MemoryBuffer, though, so we have to be careful
and give them each one of their own.
Thanks to Greg Clayton, Eric Christopher and Michael Spencer for helping
figure out what's going wrong here.

Among other differences, GCC accepts
typedef int IA[];
typedef int A10[10];
static A10 *f(void);
static IA *f(void);
void g(void) {
(void)sizeof(*f());
}
but clang used to reject it with:
invalid application of 'sizeof' to an incomplete type 'IA' (aka 'int []')
The intention of c99's 6.2.7 seems to be that we should use the composite type
and accept as gcc does.
Doing the type merging required some extra fixes:
* Use the type from the function type in initializations, even if an parameter
is available.
* Fix the merging of the noreturn attribute in function types.
* Make CodeGen handle the fact that an parameter type can be different from
the corresponding type in the function type.
