198f4507e2 Get the list of PHI node values before the basic block is split. Also, add
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

c3afd9bf4b Make this pass substantially stronger by having it delete dead return values
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.

bb2d4de409 Checkin an improvement contributed by Bill:
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.

of a test that Bill Wendling sent me from 228.5s to 105s.  Obviously there is
more improvement to be had, but this is a nice speedup which should be "felt"
by many programs.
