to more accurately describe what it does. Expand its doxygen comment
to describe what the backedge-taken count is and how it differs
from the actual iteration count of the loop. Adjust names and
comments in associated code accordingly.

them are generic changes.
- Use the "fast" flag that's already being passed into the asm printers instead
of shoving it into the DwarfWriter.
- Instead of calling "MI->getParent()->getParent()" for every MI, set the
machine function when calling "runOnMachineFunction" in the asm printers.

- Only handles cases with @try with no @catch blocks, and there are a
number of problems with the implementation. Nevertheless, this is
good enough to handled @synchronized correctly, and some other
basic uses.

- Interface is more or less like multidelta.
- Keep in mind it won't work very well; delta is O(N^2) frequently in
practice. multidelta manages to work because it folds lines to keep
N small, but this is just working on raw tokens. However, I have a
fancy pants DAG based delta algorithm which will be the bees knees
once I get it wired to clang.

that declaration to global scope so that it can be found from other
scopes. This allows us to diagnose redeclaration errors for external
declarations across scopes. We also warn when name lookup finds such
an out-of-scope declaration. This is part of <rdar://problem/6127293>;
we'll also need to do the same thing for variables.

a DBG_LABEL or not. We want to fall back to the original way of emitting debug
info when we're in -O0/-fast mode.
- Add plumbing in to pass the "Fast" flag to places that need it.
- XFAIL DebugInfo/deaddebuglabel.ll. This is finding 11 labels instead of 8. I
need to investigate still.

analyzer for array subscript expressions involving bases that are vectors. This
solution is probably a hack: it gets the lvalue of the vector instead of an
rvalue like all other types. This should be reviewed (big FIXME in
GRExprEngine).

This allows the PTH file to stay 100% in fidelity with the source code and
defines away some weird cosmetic bugs for operations such as '-E' where
maintaining knowledge of the original literal representation is useful.

- When we are declaring a function in local scope, we can merge with
a visible declaration from an outer scope if that declaration
refers to an entity with linkage. This behavior now works in C++
and properly ignores entities without linkage.
- Diagnose the use of "static" on a function declaration in local
scope.
- Diagnose the declaration of a static function after a non-static
declaration of the same function.
- Propagate the storage specifier to a function declaration from a
prior declaration (PR3425)
- Don't name-mangle "main"

size to that of the *cleaned* spelling. This way 'getSpelling()' for literals in
the Preprocessor just works and doesn't read beyond the bounds of the cached
spelling buffer.

trip counts that use signed comparisons. It's not obviously the best
approach for preserving trip count information, and at any rate there
isn't anything in the tree right now that makes use of that, so for
now always using zero-extensions is preferable.

assertion when the ivars and method list was reset into the existing
interface. To fix this, mark decls as invalid when they are redefined,
and don't insert ivars/methods into invalid decls.

so that ScalarEvolution doesn't hang onto a dangling Loop*, which
could be a problem if another Loop happens to get allocated at the
same address.
