That way, lit's builtin 'env' command can be used for the 'env' bit.
Also it's clearer that way that the 'not' shouldn't cover 'env'
failures.

Changes the default Windows target triple returned by
GetHostTriple.cmake from the old environment names (which we wanted to
move away from) to newer, normalized ones. This also requires updating
all tests to use the new systems names in constraints.

Summary:
cp -a is neither part of POSIX nor the LSB. The nearest equivalent under
POSIX is cp -RPp; however, cp -R is sufficient for the intended purpose.
test/Modules/crash-vfs-headermaps.m is not updated since it requires
system-darwin anyway.

Many of our supported configurations support modules but do not have any
first-class syntax to perform a module import. This leaves us with a problem:
there is no way to represent the expansion of a #include that imports a module
in the -E output for such languages. (We don't want to just leave it as a
#include because that requires the consumer of the preprocessed source to have
the same file system layout and include paths as the creator.)
This patch adds a new pragma:
#pragma clang module import MODULE.NAME.HERE
that imports a module, and changes -E and -frewrite-includes to use it when
rewriting a #include that maps to a module import. We don't make any attempt
to use a native language syntax import if one exists, to get more consistent
output. (If in the future, @import and #include have different semantics in
some way, the pragma will track the #include semantics.)

The most common workflow with module reproducers involves deleting the
module cache before running the script. This happens because leftovers
from the crash are present in the cache and could trigger unrelated and
confusing errors, misleading from the initial reproduction intent.
Change this to point to a clean path but leave the leftovers untouched.

The cc1 invocation in the reproducer script should contain a valid path in
-fmodule-cache-path; for that reuse "<name>.cache/module" dir we already
use to dump the vfs and modules.

The current ModuleDependencyCollector has a AST listener to collect
header files present in loaded modules, but this isn't enough to collect
all headers needed in the crash reproducer. One of the reasons is that
the AST writer doesn't write symbolic link header paths in the pcm modules,
this makes the listeners on the reader only able to collect the real files.
Since the module maps could contain submodules that use headers which
are symbolic links, not collecting those forbid the reproducer scripts
to regen the modules.
For instance:
usr/include/module.map:
...
module pthread {
header "pthread.h"
export *
module impl {
header "pthread_impl.h"
export *
}
}
...
usr/include/pthread/pthread_impl.h
usr/include/pthread_impl.h -> pthread/pthread_impl.h
The AST dump for the module above:
<SUBMODULE_HEADER abbrevid=6/> blob data = 'pthread_impl.h'
<SUBMODULE_TOPHEADER abbrevid=7/> blob data = '/<path_to_sdk>/usr/include/pthread/pthread_impl.h'
Note that we don't have "usr/include/pthread_impl.h" which is requested
by the module.map in case we want to reconstruct the module in the
reproducer. The reason the original symbolic link path isn't used is
because the headers are kept by name and requested through the
FileManager, which unique files and returns the real path only.
To fix that, add a callback to be invoked everytime a header is added
while parsing module maps and hook that up to the module dependecy
collector. This callback is only registered when generating the
reproducer.
