[DeadArgElim] Split the invoke successor edge

Invoking a function which returns an aggregate can sometimes be
transformed to return a scalar value.  However, this means that we need
to create an insertvalue instruction(s) to recreate the correct
aggregate type.  We achieved this by inserting an insertvalue
instruction at the invoke's normal successor.  However, this is not
feasible if the normal successor uses the invoke's return value inside a
PHI node.

Instead, split the edge between the invoke and the unwind successor and
create the insertvalue instruction in the new basic block.  The new
basic block's successor will be the old invoke successor which leaves
us with IR which is well behaved.

This fixes PR24906.

[SystemZ] Fix expansion of ISD::FPOW and ISD::FSINCOS

The ISD::FPOW and ISD::FSINCOS opcodes default to Legal, but there
is no legal instruction for those on SystemZ.  This could cause
LLVM internal errors.  Fixed by setting the operation action to
Expand for those opcodes.

Also added test cases for all other LLVM IR intrinsics that should
generate a library call.  (Those already work correctly since the
default operation action is fine.)
