The UserSettings controllers must be initialized & terminated in the
correct order.  Previously this was tacitly implemented but not
enforced, so it was possible to accidentally do things in the wrong
order and cause problems.  This fixes that problem.

Value, not an Instruction, so casting is not necessary. Also,
it's theoretically possible that the Value is not an
Instruction, since WeakVH follows RAUWs.

Profiling showed that 'CheckImplicitConversions' was very slow because of the call to getSpellingLoc().  On 'aes.c'
in the LLVM test suite, this function was consuming 7.4% of -fsyntax-only time.  This change fixes this issue
by delaying the check that the warning would be issued within a system macro by as long as possible.  The
main negative of this change is now the logic for this check is done in multiple places in this function instead
of just in one place up front.

after it has finished all of its reassociations, because its
habit of unlinking operands and holding them in a datastructure
while working means that it's not easy to determine when an
instruction is really dead until after all its regular work is
done. rdar://9096268.

This happens a lot in clang-compiled C++ code because it adds overflow checks to operator new[]:
  unsigned *foo(unsigned n) { return new unsigned[n]; }
We can optimize away the overflow check on 64 bit targets because (uint64_t)n*4 cannot overflow.

I have to revert this recent fix to tuple conversions until clang implements cwg 1170.  Without this fix pair and tuple don't convert properly.  With it, associative containers get access errors when they shouldn't.  cwg 1170 fixes the latter.

When doing reachability analysis for warnings issued under DiagRuntimeBehavior, don't construct a ParentMap or CFGStmtMap.
Instead, create a small set of Stmt* -> CFGBlock* mappings during CFG construction for only the statements we care about
relating to the diagnostics we want to check for reachability.

This patch supports building the Linux platform plugin, and should also support
the MacOSX plugin as well (the MacOSX side has not been tested, unfortunately).
A small typo was corrected in lldb.cpp to initialize the new platform code on
Linux.
