Subject: WebAssembly: add basic floating-point tests

Summary: I somehow forgot to add these when I added the basic floating-point opcodes. Also remove ceil/floor/trunc/nearestint for now, and add them only when properly tested.

Subscribers: llvm-commits, sunfish, jfb

Differential Revision: http://reviews.llvm.org/D11927

llvm-svn: 244562
