[bugpoint][PR29027] Reduce function attributes Summary: In addition to reducing the functions in an LLVM module, bugpoint now reduces the function attributes associated with each of the remaining functions. To test this, add a -bugpoint-crashfuncattr test pass, which crashes if a function in the module has a "bugpoint-crash" attribute. A test case demonstrates that the IR is reduced to just that one attribute.

bugpoint: Add option to disable attribute removal This takes a long time and never reduces anything useful for me (e.g. I've been waiting for 3 hours on a testcase and it hasn't found any attributes to remove yet). This should probably start by assuming no attributes matter, and adding back.

[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
