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.

; Test that bugpoint can reduce the set of functions by replacing them with null.

[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.

[Bugpoint] Only run plugins tests if plugins are enabled This is a followup to r360991 which applies the same logic to LLVM. Differential Revision: https://reviews.llvm.org/D62050 llvm-svn: 360993
