multiple edges between two blocks is linear. If the caller is iterating all
edges leaving a BB that would be a square time algorithm. It is more efficient
to have the callers handle that case.

Currently the only callers are:
* GVN: already avoids the multiple edge case.
* Verifier: could only hit this assert when looking at an invalid invoke. Since
it already rejects the invoke, just avoid computing the dominance for it.

Apply patches supplied by Michel Morin in http://llvm.org/bugs/show_bug.cgi?id=13601 to correct bugs in is_convertible for the case that the intrinsic __is_convertible_to is not available.

TargetLowering: Use the large shift amount during legalize types. The legalizer may call us with an overly large type.

Increment the MBB iterator at the top of the loop to properly handle the
current (and previous) instructions getting erased.

This fixes PR13625.

Guard MemoryBuiltins against self-looping GEPs, which can occur in unreachable code due to constant propagation.

Fixes PR13621.

I really need to find a way to automate this, but I can't come up with a regex
that has no false positives while handling tricky cases like custom check
prefixes.

Initializing a reference with itself, e.g. "int &a = a;" seems like a

Make ReplaceATOMIC_BINARY_64 a static function. Use a nested switch to reduce to only a single call to it thus allowing it to be inlined by the compiler.

reference, so &* on an empty WeakVH binds a reference to a dereferenced null

This attempts to be a higher-level description of our inlining heuristics
and decision trees than the source, where the work is spread out between
ExprEngine (mostly in ExprEngineCallAndReturn.cpp) and CallEvent, with a
few other classes participating as well.
