[PATCH] D55216: [bugpoint][PR29027] Reduce function attributes

[Brian Gesiak via Phabricator via llvm-commits]

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.
