[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.

[bugpoint] Add a named metadata (+their operands) reducer Summary: We frequently run bugpoint on a linked module that consists of all modules we create while jitting the julia standard library. This module has a very large number of compile units (10000+) in `llvm.dbg.cu`, which didn't get reduced at all, requiring manual post processing. This is an attempt to have bugpoint go through and attempt to reduce the number of global named metadata nodes as well as their operands, to cut down the number of roots for such metadata.

[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
