Justin Bogner 25463f1577 Teach users of OnDiskHashTable to define hash_value and offset types
This paves the way to making OnDiskHashTable work with hashes that are
not 32 bits wide and to making OnDiskHashTable work very large hash
tables. The LLVM change to use these types is upcoming.

Justin Bogner e1c147c3cf Reapply "OnDiskHashTable: Use EndianStream.h to write little endian ostreams"
Committed this by accident before it was done last time.

Original message:

    Rather than rolling our own functions to write little endian data
    to an ostream, we can use the support in llvm's EndianStream.h.

    No functional change.

Ben Langmuir c8130a74f4 Recommit virtual file system
Previously reverted in r201755 due to causing an assertion failure.

I've removed the offending assertion, and taught the CompilerInstance to
create a default virtual file system inside createFileManager. In the
future, we should be able to reach into the CompilerInvocation to
customize this behaviour without breaking clients that don't care.

Ben Langmuir 090610d37a Initial implementation of virtual file system

Rafael Espindola f8f91b8976 Use llvm::sys::fs::UniqueID for windows and unix.
This unifies the unix and windows versions of FileManager::UniqueDirContainer
and FileManager::UniqueFileContainer by using UniqueID.

We cannot just replace "struct stat" with llvm::sys::fs::file_status, since we
want to be able to construct fake ones, and file_status has different members
on unix and windows.

What the patch does is:

* Record only the information that clang is actually using.
* Use llvm::sys::fs::status instead of stat and fstat.
* Use llvm::sys::fs::UniqueID
* Delete the old windows versions of UniqueDirContainer and
UniqueFileContainer since the "unix" one now works on windows too.

Argyrios Kyrtzidis 3b7793797f Extend stat query APIs to explicitly specify if the query is for
a file or directory, allowing just a stat call if a file descriptor
is not needed.

Doing just 'stat' is faster than 'open/fstat/close'.
This has the effect of cutting down system time for validating the input files of a PCH.

Chandler Carruth 3a02247dc9 Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

The member variable is always "LangOpts" and the member function is always "getLangOpts".

Argyrios Kyrtzidis 11e6f0a6c3 Currently we can only remap a file by creating a MemoryBuffer and replacing the file contents with it.
Allow remapping a file by specifying another filename whose contents should be loaded if the original
file gets loaded. This allows to override files without having to create & load buffers in advance.

Douglas Gregor d2eb58abac Add support for a chain of stat caches in the FileManager, rather than
only supporting a single stat cache. The immediate benefit of this
change is that we can now generate a PCH/AST file when including
another PCH file; in the future, the chain of stat caches will likely
be useful with multiple levels of PCH files.
