Avoid producing mismatched comdats.

The problem was that given

template<typename T>
struct foo {
  ~foo() {}
};
template class foo<int>;

We would produce a alias, creating a comdat with D0 and D1, since the symbols
have to be weak. Another TU is not required to have a explicit template
instantiation definition or an explict template instantiation declaration and
for

template<typename T>
struct foo {
  ~foo() {}
};
foo<int> a;

we would produce a comdat with only one symbol in it.

now the same diagnostics is issued for duplicate function specifiers.

Add -fprofile-sample-use to Clang's driver.

This adds a new option -fprofile-sample-use=filename to Clang. It
tells the driver to schedule the SampleProfileLoader pass and passes
on the name of the profile file to use.

Add an optional mapping from source paths to source contents.

This allows compilation database implementations for distributed build
systems to hand all data to the client to make parsing independent of
the file system.
