Because of the goop involved in the EXPECT_EQ macro, we were getting the
following warning
expression with side effects has no effect in an unevaluated context
because the "I++" was being used inside of a template type:
switch (0) case 0: default: if (const ::testing::AssertionResult gtest_ar = (::testing::internal:: EqHelper<(sizeof(::testing::internal::IsNullLiteralHelper(Args[I++])) == 1)>::Compare("Args[I++]", "&A", Args[I++], &A))) ; else ::testing::internal::AssertHelper(::testing::TestPartResult::kNonFatalFailure, "../src/unittests/IR/FunctionTest.cpp", 94, gtest_ar.failure_message()) = ::testing::Message();

Instead of copying arguments from the source function to the
destination, steal them. This has a few advantages.
- The ValueMap doesn't need to be seeded with (or cleared of)
Arguments.
- Often the destination function won't have created any arguments yet,
so this avoids malloc traffic.
- Argument names don't need to be copied.
Because argument lists are lazy, this required a new
Function::stealArgumentListFrom helper.
