George Burgess IV 9b9327fe30 llvm-reduce: Add a space to an option's --help 
Otherwise, we get "filewith".

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 1c9ca7d101 [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.
