Duncan Sands 0ad7b6e773 Inlining often produces landingpad instructions with repeated ...

catch or repeated filter clauses.  Teach instcombine a bunch
of tricks for simplifying landingpad clauses.  Currently the
code only recognizes the GNU C++ and Ada personality functions,
but that doesn't stop it doing a bunch of "generic" transforms
which are hopefully fine for any real-world personality function.
If these "generic" transforms turn out not to be generic, they
can always be conditioned on the personality function.  Probably
someone should add the ObjC++ personality function.  I didn't as
I don't know anything about it.

IPO

Stop emitting instructions with the name "tmp" they eat up memory and have to be uniqued, without any benefit.

Scalar

Fold two identical set lookups into one. No functionality change.

Utils

Clean up uses of switch instructions so they are not dependent on the operand ordering. Patch by Stepan Dyatkovskiy.
