David Blaikie 357aafb566 Fix exception handling line table problems introduced by r173593 
r173593 made us a little too eager to associate all code at the end of a
function with the user-written 'return' line. This caused problems with
breakpoints as they'd be set in exception handling code preceeding the
actual non-exception return handling code, leading to the breakpoint never
being hit in non-exceptional execution.

This change restores the pre-r173593 exception handling line information where
the cleanup code is associated with the '}' not the return line.

David Blaikie 0a21d0da17 PR14566: Debug Info: avoid top level lexical blocks in functions 
One of the gotchas (see changes to CodeGenFunction) was due to the fix in
r139416 (for PR10829). This only worked previously because the top level
lexical block would set the location to the end of the function, the debug
location would be updated (as per r139416), the location would be set to
the end of the function again (but that would no-op, since it was the same
as the previous location), then the return instruction would be emitted using
the debug location.

Once the top level lexical block was no longer emitted, the end-of-function
location change was causing the debug loc to be updated, regressing that bug.

Chandler Carruth ffd5551bc7 Rewrite #includes for llvm/Foo.h to llvm/IR/Foo.h as appropriate to 
reflect the migration in r171366.

Re-sort the #include lines to reflect the new paths.

Chandler Carruth 3a02247dc9 Sort all of Clang's files under 'lib', and fix up the broken headers 
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

Eli Friedman 1f576831c9 When evaluating variably modified types for function parameters, dig out the 
type as written from the ParmVarDecl; it's unclear whether the standard
(C99 6.9.1p10) requires this, but we're following the precedent set by gcc,
and hopefully nobody will ever ask about this again.

Richard Smith b1b0ab41e7 Use the individual -fsanitize=<...> arguments to control which of the UBSan 
checks to enable. Remove frontend support for -fcatch-undefined-behavior,
-faddress-sanitizer and -fthread-sanitizer now that they don't do anything.
