Craig Topper 44d510a3c6 [RISCV] Have sexti32 also recognize AssertZExt from types smaller than i32. 
An i64 AssertZExt from a type smaller than i32 has at least 33
leading zeros which mean it has at least 33 sign bits.

Since we have a couple patterns that use two sexti32, I've
switched to a ComplexPattern so tablegen didn't have to generate
9 different permutations.

As noted in the FIXME, maybe we should just call computeNumSignBits,
but we don't have tests that benefit from that yet.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.
