baf920c9bc Add a file magic for CL.exe's object file created with /GL. 
This patch makes it possible to identify object files created by CL.exe
with /GL option. Such file contains Microsoft proprietary intermediate
code instead of target machine code to do LTO.

I need this to print out user-friendly error message from LLD.

2864c2ae90 Remove TimeValue usage from llvm/Support 
Summary:
This is a follow-up to D25416. It removes all usages of TimeValue from
llvm/Support library (except for the actual TimeValue declaration), and replaces
them with appropriate usages of std::chrono. To facilitate this, I have added
small utility functions for converting time points and durations into appropriate
OS-specific types (FILETIME, struct timespec, ...).

f84a11c301 ScanDirForExecutable on Windows fails to find executables with the "exe" extension in name 
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.

8d230cd536 Misc cleanups to the FileSytem api. 
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).
