prune-eh will not be ported to the NPM. Instead, a combination of function-attrs and simplifycfg should be used (as described in https://reviews.llvm.org/D44415). This pins most tests using -prune-eh to the legacy PM. Some of these were testing legacy PM infra (mostly the CGPassManager). Some of these can be tested in the NPM using function-attrs and simplifycfg. One interesting case is simplenoreturntest.ll. function-attrs + simplifycfg does not yet make a caller of a caller of a noreturn function end with unreachable like prune-eh does. That can be added in the future. Reviewed By: asbirlea Differential Revision: https://reviews.llvm.org/D90012
