When using lit's internal shell, RUN lines like the following
accidentally execute an external `diff` instead of lit's internal
`diff`:
```
# RUN: program | diff file -
# RUN: not diff file1 file2 | FileCheck %s
```
Such cases exist now, in `clang/test/Analysis` for example. We are
preparing patches to ensure lit's internal `diff` is called in such
cases, which will then fail because lit's internal `diff` cannot
currently be used in pipelines and doesn't recognize `-` as a
command-line option.
To enable pipelines, this patch moves lit's `diff` implementation into
an out-of-process script, similar to lit's `cat` implementation. A
follow-up patch will implement `-` to mean stdin.

This enables lit to work with unicode file names via mkdir, rm, and redirection.
Lit still uses utf-8 internally, but converts to utf-16 on Windows, or just utf-8
bytes on everything else.

Make sure all print statements are compatible with Python 2 and Python3 using
the `from __future__ import print_function` statement.
Differential Revision: https://reviews.llvm.org/D56249
llvm-svn: 350307
Summary:
In Python2 'unicode' is a distinct type from 'str', but in Python3 'unicode' does not exist and instead all 'str' objects are Unicode string. This change updates the logic in the test logging for lit to correctly process each of the types, and more importantly, to not just fail in Python3.
This change also reverses the use of quotes in several of the cfg files. By using '""' we are guaranteeing that the resulting path will work correctly on Windows while "''" only works correctly sometimes. This also fixes one of the failing tests.

Summary:
The issue with the python path is that the path to python on Windows can contain spaces. To make the tests always work, the path to python needs to be surrounded by quotes.
This change updates several configuration files which specify the path to python as a substitution and also remove quotes from existing tests.

(Relands r333584, reverted in 333592.)
When debugging test failures with -vv (or -v in the case of the
internal shell), this makes it easier to locate the RUN line that
failed. For example, clang's test/Driver/linux-ld.c has 892 total RUN
lines, and clang's test/Driver/arm-cortex-cpus.c has 424 RUN lines
after concatenation for line continuations.
When reading the generated shell script, this also makes it easier to
locate the RUN line that produced each command.
To support reporting RUN line numbers in the case of the internal
shell, this patch extends the internal shell to support the null
command, ":", except pipelines are not supported.
To support reporting RUN line numbers in the case of windows cmd.exe
as the external shell, this patch extends -vv to set "echo on" instead
of "echo off" in bat files. (Support for windows cmd.exe as a lit
external shell will likely be dropped later, but I found out too
late.)
