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.

As it's causing some bot failures (and per request from kbarton).
This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

Summary:
If the normal destination of the invoke or the parent block of the call site is unreachable-terminated, there is little point in inlining the call site unless there is literally zero cost. Unlike my previous change (D15289), this change specifically handle the call sites followed by unreachable in the same basic block for call or in the normal destination for the invoke. This change could be a reasonable first step to conservatively inline call sites leading to an unreachable-terminated block while BFI / BPI is not yet available in inliner.
