Bring inheriting constructor implementation up-to-date with current defect
reports, and implement implicit definition of inheriting constructors.
Remaining missing features: inheriting constructor templates, implicit
exception specifications for inheriting constructors, inheriting constructors
from dependent bases.

This code works around what appears to be a bug in another part of clang.
I have filed http://llvm.org/bugs/show_bug.cgi?id=15538 against clang.
This code is safer anyway because "cast" assumes you really know that
it's okay to make the cast. In this case isa should not be false and
dyn_cast should not return null as far as I understand. But everything
else is valid so I did not want to revert my previous patch for attributes
mips16/nomips16 or use an llvm_unreachable here which would make a number
of our tests fail for mips.

Add missing diagnostic for a nested-name-specifier on a free-standing type definition. Bump some related diagnostics from warning to extension in C++, since they're errors there. Add some missing checks for function specifiers on non-function declarations.

PR15539: Record "evaluating if/elif condition" flag in the right place

The previous implementation missed the case where the elif condition was
evaluated from the context of an #ifdef that was false causing PR15539.

[analyzer] Do part of the work to find shortest bug paths up front.

Splitting the graph trimming and the path-finding (r177216) already
recovered quite a bit of performance lost to increased suppression.
We can still do better by also performing the reverse BFS up front
(needed for shortest-path-finding) and only walking the shortest path
for each report. This does mean we have to walk back up the path and
invalidate all the BFS numbers if the report turns out to be invalid,
but it's probably still faster than redoing the full BFS every time.

More performance work for <rdar://problem/13433687>

PR15383: When -fsanitize=float-cast-overflow checks a float-to-int conversion,
it wasn't taking into account that the float should be truncated *before* the
range check happens. Thus (unsigned)-0.99 and (unsigned char)255.9 have defined
behavior and should not be trapped.
