Peter Collingbourne aaeb73b159 Introduce CompilerInvocation::setLangDefaults function
This patch refactors the CompilerInvocation code to introduce a
CompilerInvocation::setLangDefaults function, which can set up a
LangOptions with the defaults for a given language and language
standard.  This function is useful for non-command line based Clang
clients which need to set up a CompilerInvocation manually for a
specific language.

Fariborz Jahanian e8473c2feb Such function decls,as objc's objc_msgSend, builtins in

extensing Builtins.def and via a language flag added
to LIBBUILTIN/BUILTIN and check for that when deciding
a name is builtin or not. Implements //rdar://8689273.

Douglas Gregor f88e35ba0b When using a precompiled preamble with detailed preprocessing records,
trap the serialized preprocessing records (macro definitions, macro
instantiations, macro definitions) from the generation of the
precompiled preamble, then replay those when walking the list of
preprocessed entities. This eliminates a bug where clang_getCursor()
wasn't able to find preprocessed-entity cursors in the preamble.

Douglas Gregor 936a5b44ee When loading a precompiled preamble, use the file ID of the
precompiled preamble as the "main" source file's file ID within the
source manager. This makes compiling with a precompiled preamble
produce the same source locations as when compiling without the
precompiled preamble; prior to this change, we ended up with different
file IDs for source locations within the precompiled preamble
vs. those after the precompiled preamble, even for entities (e.g.,
preprocessing entities) in the same file.

John McCall 9b66c4bbbe Add -cc1 -ast-dump-xml, an excessively detailed XML dump of the internals
of the ASTs.  Only available in assertions builds.  No stability guarantee.

This is intended solely as a debugging tool.  I'm not sure if the goals
are sufficiently aligned with the XML printer to allow a common
implementation.

Currently just falls back on the StmtDumper to display statements,
which means it doesn't produce valid XML in those cases.

Chris Lattner 4ac569b2c6 Partially revert Doug's PCH validation patch (r98585).
This patch completely defeated the "passing in a prestat'd size 
to MemoryBuffer" optimization, leading to an extra fstat call for
every buffer opened, in order to find out if the datestamp and size 
of the file on disk matches what is in the stat cache.

I fully admit that I don't completely understand what is going on here:
why punish code when a stat cache isn't in use?  what is the point of a
stat cache if you have to turn around and stat stuff to validate it?

To resolve both these issues, just drop the modtime check and check the
file size, which is the important thing anyway.  This should also resolve
PR6812, because presumably windows is stable when it comes to file sizes.
If the modtime is actually important, we should get it and keep it on the
first stat.

This eliminates 833 fstat syscalls when processing Cocoa.h, speeding up
system time on -Eonly Cocoa.h  from 0.041 to 0.038s.

Craig Silverstein 1a9ca21881 Several PPCallbacks take an SourceLocation + IdentifierInfo, rather
than a Token that holds the same information all in one easy-to-use
package.  There's no technical reason to prefer the former -- the
information comes from a Token originally -- and it's clumsier to use,
so I've changed the code to use tokens everywhere.

other platforms where the textual default of '/' isn't the system's root
directory. We should probably still make the textual default platform specific,
but this should avoid the particularly bad problem with the previous state: we
applied a sysroot of '/' to '/usr/local/google' which added
'//usr/local/include' to the windows header search path, a share on another
machine named 'usr'. Oops.

Argyrios Kyrtzidis 71731d6b05 Implement -working-directory.
When -working-directory is passed in command line, file paths are resolved relative to the specified directory.
This helps both when using libclang (where we can't require the user to actually change the working directory)
and to help reproduce test cases when the reproduction work comes along.

--FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains
 the working directory value if set).
--FileSystemOptions are passed around to various interfaces that perform file operations.
--Opening & reading the content of files should be done only through FileManager. This is useful in general since
 file operations will be abstracted in the future for the reproduction mechanism.

FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same
FileManager but with different FileSystemOptions.

Addresses rdar://8583824.

Douglas Gregor bb6a881862 Fix three related, wily issues with the recompilation of precompiled
preambles:

  - When we rebuild a precompiled preamble, make sure to disable
    skipping anything in the main file; we may have had leftover
    preamble-skipping values in the lexer, which leads to very empty
    preamble. This is a correctness issue.

  - When we rebuild a precompiled preamble, clear out any prior state
    in the Diagnostic object. Otherwise, we might think that there
    were errors when we were building the preamble itself, and
    therefore reject the resulting preamble. This is mainly a
    performance issue.

  - Don't remove old remappings when digging out the remapping for the
    main file. Having the old mappings around does not hurt in the
    common case (later remappings will just overwrite them), and is
    important when we fail to find a preamble: we don't want to have
    removed the remapping, because we'll need it later.

Douglas Gregor 2fb99df2c3 When setting the globally-visible declarations for a particular
identifier, we may have a Sema object but no translation unit scope
(because parsing is finished). In this case, we still need to update
the IdResolver, which might still be used when writing a PCH
containing another PCH (without chaining). This bug manifested as a
failure with precompiled preambles.

Also, add a little environment-variable-sensitive logging for
libclang.

Douglas Gregor 0ac41389a4 Synchronize globally-cached code completion results with the results
provided when the optimization is disabled. In particular, split
the completion context CCC_Other into two contexts: CCC_Other, which

unwelcome, and CCC_Recovery, which is used in recovery cases.

Since we're now using the completion context within the completion
results builder, make sure that it's always set to something.

Douglas Gregor 250ab1dc0e The two libclang crash-recovery tests that involve precompiled
preambles end up leaving the precompiled preambles around. This is by
design, since we do minimal cleanup during crash recovery. However,
it's unfortunate for testing, so introduce a hook that allows these
two tests to put the precompiled preamble somewhere where we can
delete them after testing.
