David Blaikie f27367cd32 llvm-reduce: Clean out previous test temp/output dir, since it was a dir and now it's used as just a single file

David Blaikie cb4aee7318 llvm-reduce: Make tests shell-independent by passing the interpreter on the command line rather than using #! in the test file

Tim Shen 396d0e1635 Fix llvm-reduce tests so that they don't assume the source code is 
writable.

Instead of copying over the original file permissions, just create
a new file and add the executable bit.

David Blaikie 6be90ac788 llvm-reduce: For now, mark these tests as requiring a shell 
(since they execute shell scripts/that's the only entry point at the
moment)

David Blaikie aaef97a55e PR43278: llvm-reduce: Use temporary file names (and ToolOutputFile) rather than unique ones - to ensure they're cleaned up 
This modifies the tool somewhat to only create files when about to run
the "interestingness" test, and delete them immediately after - this
means some more files will be created sometimes (when "double checking"
work - which should probably be fixed/avoided anyway).

This now creates temporary files, rather than only unique ones, and also
uses ToolOutputFile (without ever calling "keep") to ensure the files
are deleted as soon as the interestingness test is run.

David Blaikie 699bea494c llvm-reduce: Simplify testing using -implicit-check-not 
Also fix llvm-reduce to use the specified output file name directly,
without appending '.ll' to the name.

Diego Trevino Ferrer c26892538e [Bugpoint redesign] Output option can now print to STDOUT 
Summary:
This also changes all the outs() statements to errs() so the output and
progress streams don't get mixed.

This has been added because D64176 had flaky tests, which I believe were because the reduced file was being catted into `FileCheck`, instead of being pass from STDOUT directly.

Diego Trevino Ferrer ef4ad1a8b6 Revert [Bugpoint redesign] Added Pass to Remove Global Variables 
This reverts r368918 because it was unstable!

It broke these builds:
 * http://lab.llvm.org:8011/builders/lld-x86_64-ubuntu-fast/builds/4649
 * http://lab.llvm.org:8011/builders/clang-ppc64be-linux-lnt/builds/29966
 * http://lab.llvm.org:8011/builders/clang-ppc64be-linux-lnt/builds/29964

But surprisingly this passed:

Diego Trevino Ferrer d1ffcd0745 [Bugpoint redesign] Added Pass to Remove Global Variables 
Summary:
This pass tries to remove Global Variables, as well as their derived uses. For example if a variable `@x` is used by `%call1` and `%call2`, both these uses and the definition of `@x` are deleted. Moreover if `%call1` or `%call2` are used elsewhere those uses are also deleted, and so on recursively.

I'm still uncertain if this pass should remove derived uses, I'm open to suggestions.
