Rewrite the write-to-stderr.sh and write-to-stdout-and-stderr.sh shell
scripts as python scripts and call python on them.
Fixes PR33940
llvm-svn: 309200
Summary:
rL257221 attempted to run lit's own test suite continuously, but that
commit was reverted because lit's test suite does not pass on Windows.
Because lit's tests do not run continuously, they often regress.
In order to un-revert rL257221, mark lit tests that fail as XFAIL for
Windows platforms.
Test Plan:
On a Windows development environment, follow the instructions in
utils/lit/README.txt to run lit's test suite:
```
utils/lit/lit.py \
--path /path/to/your/llvm/build/bin \
utils/lit/tests
```
Verify that the test suite is run and a successful exit code is
returned.

- This will cause lit to automatically include the first 1K of data in
redirected output files when a command fails (previously if the command
failed, but the main point of the test was, say, a `FileCheck` later on, then
the log wasn't helpful in showing why the command failed).

- This only applies to scripts executed by the _internal_ shell script
interpreter.
- This patch reworks the log to look more like a shell transcript, and be less
verbose (but in the interest of calling attention to the important parts).
Here is an example of the new format, for commands with/without failures and
with/without output:
```
$ true
$ echo hi
hi
$ false
note: command had no output on stdout or stderr
error: command failed with exit status 1
```
