Summary: Moved Explicit Locals pass to last. Made that pass obligatory. Made it convert from register to stack based instructions, and removed the registers. Fixes to related code that was expecting register based instructions. Added the correct testing flag to all tests, depending on what the format they were expecting so far. Translated one test to stack format as example: reg-stackify-stack.ll tested: llvm-lit -v `find test -name WebAssembly` unittests/MC/* Reviewers: dschuff, sunfish Subscribers: jfb, llvm-commits, aheejin, eraman, jgravelle-google, sbc100 Differential Revision: https://reviews.llvm.org/D50568 llvm-svn: 339474
