When the driver tries to locate a program by its name, e.g. a linker, it
scans the paths provided by the toolchain using the ScanDirForExecutable
function. If the lookup fails, the driver uses
llvm::sys::findProgramByName. Unlike llvm::sys::findProgramByName,
ScanDirForExecutable is not aware of file extensions. If the program has
the "exe" extension in its name, which is very common on Windows,
ScanDirForExecutable won't find it under the toolchain-provided paths.
This patch changes the Windows version of the "`can_execute`" function
called by ScanDirForExecutable to respect file extensions, similarly to
llvm::sys::findProgramByName.

The main difference is the removal of
std::error_code exists(const Twine &path, bool &result);
It was an horribly redundant interface since a file not existing is also a valid
error_code. Now we have an access function that returns just an error_code. This
is the only function that has to be implemented for Unix and Windows. The
functions can_write, exists and can_execute an now just wrappers.
One still has to be very careful using these function to avoid introducing
race conditions (Time of check to time of use).

Some versions of Android don't have futimes/futimens and this code wasn't
updated during the recent errc refactoring.

Before this patch, if 'nul' was passed in input to clang, function
getStatus() (in Path.inc) always returned an instance of file_status with
field 'nFileSizeHigh' and 'nFileSizeLow' left uninitialized.
This was causing the triggering of an assertion failure in MemoryBuffer.cpp due
to an invalid FileSize for device 'nul'.
This patch fixes the assertion failure modifying the constructors of class
file_status (in llvm/Support/FileSystem.h) so that every field of the class
gets initialized to zero by default.
A clang test will be submitted on a separate patch.
