"blockaddress" can not apply to an external function. All
blockaddress constant uses must belong to the same module as the
definition of the target function.

Only force "extern" linkage if the function used to be a definition
in the source module. Declarations keep their original linkage.

Personality is copied as part of copyFunctionAttributes, but it is
invalid on a declaration. Remove the personality attribute it the
function body is not cloned.
Also add a verifier run over output modules in the llvm-split tool.

Summary:
Currently llvm::SplitModule as the first step globalizes all local objects, which might not be desirable in some scenarios.
This change adds a new flag to llvm::SplitModule that uses SCC approach to search for a balanced partition without the need to externalize symbols.
Such partition might not be possible or fully balanced for a given number of partitions, and is a function of the module properties (global/local dependencies within the module).

We had two code paths. One would create names like "foo.1" and the other
names like "foo1".
For globals it is important to use "foo.1" to help C++ name demangling.
For locals there is no strong reason to go one way or the other so I
kept the most common mangling (foo1).

The module splitter splits a module into linkable partitions. It will
be used to implement parallel LTO code generation.
This initial version of the splitter does not attempt to deal with the
somewhat subtle symbol visibility issues around module splitting. These
will be dealt with in a future change.
