This is in braces so that it doesn't conflict with the existing %p.
It uses braces instead of parens because parens would have to be
regex-escaped.

We can simply confirm the handle released to open it with EXCLUSIVE. Attempting renaming was bad.
Disable win32file at ImportError. Thanks to Francois to let me know.
FIXME: Could we report warning or notification if win32file were not found?

In previous case,
RUN: foo -o %t
RUN: FileCheck < %t
RUN: bar -o %t
2nd read handle might prevent manipulation of 3rd %t in bar, to remove and rename.

1. Added a status note when a config file is loaded directly with load_config. This helps notice loads of lit.cfg from lit.site.cfg
2. Added a status note on the result of a config load. Previously, it was just notifying that it tries to load a config file. Now it will also say whether the load succeeded or the file wasn't found
The two changes give better visibility into which config files were actually loaded by lit. The effect is only on --debug runs.

When wait() has finished, opened handles (especially writing stdout to file) might not be released immediately.
To wait for released, poll to attempt renaming.

On Python-w32 with mingw msys bash, %T was replaced to "x:\foo\bar...". msys bash cannot handle DOSish paths.

Win32 GetTempPath() tends to pick up %WINDIR% when neither TEMP nor TMP was found. %WINDIR% should not be treated writable on recent Windows OS.

Take #2. Don't piggyback on the existing config.build_mode. Instead,
define a new lit feature for each build feature we need (currently
just "asserts"). Teach both autoconf'd and cmake'd Makefiles to define
this feature within test/lit.site.cfg. This doesn't require any lit
harness changes and should be more robust across build systems.

This required chaining test configuration properties. It seems like a
generally good thing to do.

FIXME: It does not improve MSVC's issue.
[Danil Malyshev] Defining PRINTF_EXPONENT_DIGITS env is the suggested way to make MinGW ANSI/POSIX compatible. This is not only about the case we are discussing, but in general, I'd like to have explicitly defined compatibility mode for all the tests running on MinGW.

It seeks tools(eg. [cmp, grep, sed]) in same directory, to be sane.
It seeks "bash" only in the directory found at last time. Or bash would be insane (against other tools).

checkToolsPath(dir,tools):
return True if "dir" contains all "tools".
whichTools(tools,paths):
return a directory that contains all "tools" in "paths".
Or return None when all "tools" were not met.

some random tools that might happen to be in the user's PATH. This
makes LLVM testing much more stable and predictable.

On MSVS8, ${CMAKE_CFG_INTDIR}, aka $(OutDir), has capitalized name(eg. Debug), although $(OutDir) is made with lower case(eg. debug).

shell runner.
We would inadvertently end up holding on to handles to the temporary files
longer than we should have been. On Win32, where open handles lock some file
operations, this caused problems in tests which would try to move temporary
files around (as Clang does by default now).
Many thanks to Francois Pichet for the excellent detective work on this.
