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

Fixing a couple of asan-identified bugs
* use of an invalid "Use" iterator after the element was removed
* use of StringRef to Function name after the Function was erased
This reapplies r371567, which was reverted in r371580.

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.

Also fix llvm-reduce to use the specified output file name directly,
without appending '.ll' to the name.

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.

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.
