Fix PR58

llvm-svn: 9530

PHI node entries for unwind instructions just like for call instructions which
became invokes!  This fixes PR57, tested by
Inline/2003-10-26-InlineInvokeExceptionDestPhi.ll

as well as arguments.  Now it can delete arguments and return values which are
only passed into other arguments or are returned, if they are dead.  This causes
it to delete several hundred extra args/retvals from the C++ hello world program,
shrinking it by about 2K.

Only transform call sites in a setjmp'ing function which are reachable from
the setjmp.  If the call dominates the setjmp (for example), the called
function cannot longjmp to the setjmp.

This dramatically reduces the number of invoke instructions created in some
large testcases.

This implements testcase LoopSimplify/single-backedge.ll and closes PR#34
