Add support for custom names for library functions in TargetLibraryInfo.  Add a custom name for fwrite and fputs on x86-32 OSX.  Make SimplifyLibCalls honor the custom
names for fwrite and fputs.

Fixes <rdar://problem/9815881>.

the thread specific data and were destroying the thread specfic data more
than once.

Also added the ability to ask a lldb::StateType if it is stopped with an
additional paramter of "must_exist" which means that the state must be a
stopped state for a process that still exists. This means that eStateExited
and eStateUnloaded will no longer return true if "must_exist" is set to true.

 - Motivation is explained in the README, but basically it is convenient to be
   able to build compiler-rt free standing. Since our external dependencies are
   so small, we can achieve this relatively easily by just stubbing out the
   declarations of the external dependencies.
 - This is in no way, shape, or form intended to be complete, it is just the
   minimal stubs necessary to support the stuff we use.

completion information between different AST
contexts.  It works like this:

- If a Decl is imported from a context that
  has completion metadata, then that Decl
  is associated with the same completion
  information (possibly none) as the Decl
  it was imported from.

- If a Decl is imported from a context that
  does not have completion metadata, then it
  is marked as completable by consulting the
  Decl and context it was imported from.

for each AST context it knows about in a single
object.  This makes it faster to look up the
appropriate ASTImpoter for a given ASTContext
pair and also makes it much easier to delete all
metadata for a given AST context.

In the future, this fix will allow the
ClangASTImporter to propagate completion
information between the metadata for different
AST contexts as its minions move AST objects
around.

The code for checking Neon builtin pointer argument types was assuming that
there would only be one pointer argument.  But, for vld2-4 builtins, the first
argument is a special sret pointer where the result will be stored.  So,
instead of scanning all the arguments to find a pointer, have TableGen figure
out the index of the pointer argument that needs checking.  That's better than
scanning all the arguments regardless.  <rdar://problem/10448804>

states misses when folded/dead instructions are present), but it is a step in
the right direction.
