llvm-svn: 298566

Summary:
This patch adopts the recent changes that renamed `set_exception(exception_pointer)` to `unhandled_exception()`. 

Additionally `unhandled_exception()` is now required, and so an error is emitted when exceptions are enabled but the promise type does not provide the member.
When exceptions are disabled a warning is emitted instead of an error, The warning notes that the `unhandled_exception()` function is required when exceptions are enabled.

Summary:
This removes the 'remapTypeIndices' method on every TypeRecord class. My
original idea was that this would be the beginning of some kind of
generic entry point that would enumerate all of the TypeIndices inside
of a TypeRecord, so that we could write generic graph algorithms for
them without duplicating the knowledge of which fields are type index
fields everywhere. This never happened, and nothing else uses this
method. I need to change the API to deal with merging into IPI streams,
so let's move it into the file that uses it first.

Summary:
Adding a printer pass for printing the LVI cache values after transformations
that use LVI.
This will help us in identifying cases where LVI
invariants are violated, or transforms that leave LVI in an incorrect state.
Right now, I have added two test cases to show that the printer pass is working.
I will be adding more test cases in a later change, once this change is
checked in upstream.

This #include was the cause of a dependency from Symbol ->
DataFormatters.  However, nothing from the header was being
used anyway, so we can just remove it with no adverse effects.

This reduces the overall cycle count from 44 to 43.

It seems MS headers have started using __readgsqword, and since it's
used in a header that doesn't include intrin.h, we can't implement it as
an inline function anymore.

That was already the case for __readfsdword, which Saleem added support
for in r220859. This patch reuses that codegen to implement all of
__read[fg]s{byte,word,dword,qword}.
