David Tenty 82d3c0759f [AIX] Add %pluginext and update tests to use proper pluginext 
As a follow on to D96282, since bug point passes is built as a module the proper file extension to use is LLVM_PLUGIN_EXT, rather than SHLIBEXT. Using SHLIBEXT causes the tests to load a non-existent file on AIX. We also adjust the PluginsTest unittest  to use LLVM_PLUGIN_EXT for similar reasons.

This change should hopefully make little difference to other platforms, since generally `SHLIBEXT=LTDL_SHLIB_EXT=CMAKE_SHARED_LIBRARY_SUFFIX` and `LLVM_PLUGIN_EXT=CMAKE_SHARED_LIBRARY_SUFFIX` on every platform except AIX.

Brian Gesiak 5cc8920d02 [bugpoint] Find 'opt', etc., in bugpoint directory 
Summary:
When bugpoint attempts to find the other executables it needs to run,
such as `opt` or `clang`, it tries searching the user's PATH. However,
in many cases, the 'bugpoint' executable is part of an LLVM build, and
the 'opt' executable it's looking for is in that same directory.

Many LLVM tools handle this case by using the `Paths` parameter of
`llvm::sys::findProgramByName`, passing the parent path of the currently
running executable. Do this same thing for bugpoint. However, to
preserve the current behavior exactly, first search the user's PATH,
and then search for 'opt' in the directory containing 'bugpoint'.

Test Plan:
`check-llvm`. Many of the existing bugpoint tests no longer need to use the
`--opt-command` option as a result of these changes.

Vedant Kumar 67fdb6b82a [bugpoint] Avoid noisy errors by passing a valid opt to tests 
If the tests don't use the in-tree opt, we're liable to see some silly
error messages due to the version mismatch (missing flags, etc).

JF Bastien f87e20dd87 bugpoint Enhancement. 
Summary:
This patch adds two flags to `bugpoint`: "-replace-funcs-with-null" and "-disable-pass-list-reduction".

When "-replace-funcs-with-null" is specified, bugpoint will, instead of simply deleting function bodies, replace all uses of functions and then will delete functions completely from the test module, correctly handling aliasing and @llvm.used && @llvm.compiler.used. This part was conceived while trying to debug the PNaCl IR simplification passes, which don't allow undefined functions (ie no declarations).

With "-disable-pass-list-reduction", bugpoint won't try to reduce the set of passes causing the "crash". This is needed in cases where one is trying to debug an issue inside the PNaCl IR simplification passes which is causing an PNaCl ABI verification error, for example.
