When CodeExtractor outlines values which are used by the original
function, it must store those values in some in-out parameter. This
store instruction must not be inserted in between a PHI and an EH pad
instruction, as that results in invalid IR.
This fixes the following verifier failure seen while outlining within
ObjC methods with live exit values:
The unwind destination does not have an exception handling instruction!
%call35 = invoke i8* bitcast (i8* (i8*, i8*, ...)* @objc_msgSend to i8* (i8*, i8*)*)(i8* %exn.adjusted, i8* %1)
to label %invoke.cont34 unwind label %lpad33, !dbg !4183
The unwind destination does not have an exception handling instruction!
invoke void @objc_exception_throw(i8* %call35) #12
to label %invoke.cont36 unwind label %lpad33, !dbg !4184
LandingPadInst not the first non-PHI instruction in the block.
%3 = landingpad { i8*, i32 }
catch i8* null, !dbg !1411
