The makefile build system had two lists of the 32-bit runtime libraries
to build and one had grown out of sync. Put this list in a variable so
this doesn't happen again.

The whole thing here is somewhat suspicious as we don't support 32-bit
environments with a 64-bit bi-arch capable compiler, but none have
complained yet about this so I'm just leaving it alone.

Fix the addition of Clang's profile runtime library to the link step
when specifying --coverage (or related) flags.

The system for doing this was based on the old LLVM-hosted profile_rt
library, and hadn't been updated for Linux to use the new compiler-rt
library. Also, it couldn't possibly work on multiarch or biarch systems
in many cases. The whole thing now works much the same as the sanitizer
libraries that are built and used out of the compiler-rt repo.

Note that other target OSes haven't been updated because I don't know if
they're doing anything special with the installation path of profile_rt.
I suspect however that *all* of these are wrong and would encourage
maintainers of each target to take a hard look at how compiler-rt
runtime libraries are linked on their platforms.

Documentation parsing: recognize \relates, \related, \relatesonly, \relatedonly

Add -ast-dump-lookups switch to -cc1 to dump DeclContext lookup maps. Test to
follow.

When setting the external visible declarations for a decl context, check
whether they replace any existing lookups in the context, rather than
accumulating a bunch of lookup results referring to the same entity.

DebugInfo: Merge a bad debug info enum test into a good one

The assembly generation testing has been moved to an LLVM test case.

DebugInfo: ensure negative enumerators are emitted as such

There's still a problem here - since we're not appropriately using the
signedness/range of the enum to chooset the encoding and emission of
enumerators, but GCC has some bugs around this too so I assume that's
not /such/ a high priority though I may get to it soon out of
completeness.

Avoid adding entries to the DeclContext lookup table multiple times when lazily
constructing a lookup table.

Previously, buildLookup would add lookup table entries for each item lexically
within the DC, and adding the first entry with a given name would trigger the
external source to add all its entries with that name. Then buildLookup would
carry on and re-add those entries all over again.

Instead, follow a simple rule: a declaration from an external source is only
ever made visible by the external source. One exception to this: since we don't
usually build a lookup table for the TU in C, and we never serialize one, we
don't expect the external source to provide lookups in the TU in C, so we build
those ones ourselves.

The profile library must come before the C library so that it can use
atexit.
