5af94066ee we already know the sectionkind when invoking SelectSectionForGlobal, 
pass it in instead of recomputing it.

7d304b8e4e There is no need to pass the name into lib/Target/TargetAsmInfo.cpp 
when we have a global with no section explicitly specified.

4bb9a9a7d3 Replace UniqueSectionForGlobal with getSectionPrefixForUniqueGlobal. 
The later doesn't depend on any crazy LLVM IR stuff, and this
pulls the concatenation of prefix with GV name (the root problem behind
PR4584) out one level.

f4838d90e4 Revert r75581: it causes massive breakage in the Ada 
testsuite, due to exception handling not working
correctly.  Maybe because the libgcc unwinder is
miscompiled - not sure, and I won't have time to
look into it before leaving on holiday.  Note that
miscompilations of libgcc are not picked up by the
nightly testers, because they dynamically link with
libgcc, so pick up the system version rather than
the version built as part of llvm-gcc.  This is a
nasty flaw in the nightly testers.  (On the other
hand the Ada testsuite links with the just built
libgcc).

8997f6bfc1 Since we have moved unified assembly, switch to ADR instruction instead of a the difficult-to-read .set + add syntax to materialize pc-relative address. 
Turns out this also fixed a poor code selection on Thumb1. I have no idea why we were using a mov + add to do the same thing as ADR before.
