Douglas Gregor d6f8124c9c Eliminate the internal command-line option for viewing inheritance in C++ classes, since it's only really worked for the trivial cases anyway due to lame pseudo-parsing of the class name.

Douglas Gregor e5de7013c7 Remove the last virtual member function from the Decl hierarchy,
reducing the size of all declarations by one pointer. For a 64-bit
Clang parsing Cocoa.h, this saves ~630k of memory (about 3.5% of
ASTContext's memory usage for this header).

Chandler Carruth 22c7a79a1d Implement a sub-group of -Wconversion: -Wliteral-conversion. This
specifically targets literals which are implicitly converted, a those
are more often unintended and trivial to fix. This can be especially
helpful for diagnosing what makes 'const int x = 1e6' not an ICE.

Original patch authored by Jim Meehan with contributions from other
Googlers and a few cleanups from myself.

John McCall c07a0c7e48 Change the representation of GNU ?: expressions to use a different expression
class and to bind the shared value using OpaqueValueExpr.  This fixes an
unnoticed problem with deserialization of these expressions where the
deserialized form would lose the vital pointer-equality trait;  or rather,
it fixes it because this patch also does the right thing for deserializing
OVEs.

Change OVEs to not be a "temporary object" in the sense that copy elision is
permitted.

This new representation is not totally unawkward to work with, but I think
that's really part and parcel with the semantics we're modelling here.  In
particular, it's much easier to fix things like the copy elision bug and to
make the CFG look right.

I've tried to update the analyzer to deal with this in at least some          
obvious cases, and I think we get a much better CFG out, but the printing
of OpaqueValueExprs probably needs some work.

Chandler Carruth 712563bba4 Implement -Wenum-compare, which warns when comparing two enums of
different types. We omit the warning when the enum types are anonymous.
Unlike GCC, this warning does not distinguish between C++ and C/ObjC for
controling whether it is on by default, it is always on by default.

style issues, and cleaned it up for submission.

Chris Lattner c8e630e4db Step #1/N of implementing support for __label__: split labels into
LabelDecl and LabelStmt.  There is a 1-1 correspondence between the
two, but this simplifies a bunch of code by itself.  This is because
labels are the only place where we previously had references to random
other statements, causing grief for AST serialization and other stuff.

This does cause one regression (attr(unused) doesn't silence unused
label warnings) which I'll address next.

This does fix some minor bugs:
1. "The only valid attribute " diagnostic was capitalized.
2. Various diagnostics printed as ''labelname'' instead of 'labelname'
3. This reduces duplication of label checking between functions and blocks.

Review appreciated, particularly for the cindex and template bits.

Douglas Gregor b0f2ea9e9e When printing a qualified type, look through a substituted template
parameter type to see what's behind it, so that we don't end up
printing silly things like "float const *" when "const float *" would
make more sense. Also, replace the pile of "isa" tests with a simple
switch enumerating all of the cases, making a few more obvious cases
use prefix qualifiers.

Argyrios Kyrtzidis 556c45e9c5 [analyzer] Overhauling of the checker registration mechanism.
-Checkers will be defined in the tablegen file 'Checkers.td'.
-Apart from checkers, we can define checker "packages" that will contain a collection of checkers.
-Checkers can be enabled with -analyzer-checker=<name> and disabled with -analyzer-disable-checker=<name> e.g:
	Enable checkers from 'cocoa' and 'corefoundation' packages except the self-initialization checker:
	-analyzer-checker=cocoa -analyzer-checker=corefoundation -analyzer-disable-checker=cocoa.SelfInit
-Introduces CheckerManager and CheckerProvider. CheckerProviders get the set of checker names to enable/disable and
 register them with the CheckerManager which will be the entry point for all checker-related functionality.

Currently only the self-initialization checker takes advantage of the new mechanism.

John McCall c146582e60 When parsing an out-of-line member function declaration, we must delay
access-control diagnostics which arise from the portion of the declarator
following the scope specifier, just in case access is granted by
friending the individual method.  This can also happen with in-line
member function declarations of class templates due to templated-scope
friend declarations.

We were really playing fast-and-loose before with this sort of thing,
and it turned out to work because *most* friend functions are in file
scope.  Making us delay regardless of context exposed several bugs with
how we were manipulating delay.  I ended up needing a concept of a
context that's independent of the declarations in which it appears,
and then I actually had to make some things save contexts correctly,
but delay should be much cleaner now.

I also encapsulated all the delayed-diagnostics machinery in a single
subobject of Sema;  this is a pattern we might want to consider rolling
out to other components of Sema.

- renaming some private data members of FileManager to match their roles better.

- creating 'DirectorEntry's for the parent directories of virtual
files, such that we can tell whether two virtual files are from the
same directory.  This is useful for injecting virtual files whose
directories don't exist in the real file system.

- minor clean-ups and adding comments for class
FileManager::UniqueDirContainer and FileManager::UniqueFileContainer.

- adding statistics on virtual files to FileManager::PrintStats().

- adding unit tests to verify the existing and new behavior of FileManager.

we would deserialize all of the macro definitions we knew about while

a performance problem.

Now, we do the standard AST/PCH chaining trick: watch what identifiers
are deserialized as macro names, and consider only those identifiers
(along with macro definitions that have been deserialized/written in
the source) when serializing the preprocessor state.

Douglas Gregor 09b6989ef0 Implement two related optimizations that make de-serialization of
AST/PCH files more lazy:
  - Don't preload all of the file source-location entries when reading
  the AST file. Instead, load them lazily, when needed.
  - Only look up header-search information (whether a header was already
  #import'd, how many times it's been included, etc.) when it's needed
  by the preprocessor, rather than pre-populating it.

Previously, we would pre-load all of the file source-location entries,
which also populated the header-search information structure. This was
a relatively minor performance issue, since we would end up stat()'ing
all of the headers stored within a AST/PCH file when the AST/PCH file
was loaded. In the normal PCH use case, the stat()s were cached, so
the cost--of preloading ~860 source-location entries in the Cocoa.h
case---was relatively low.

However, the recent optimization that replaced stat+open with
open+fstat turned this into a major problem, since the preloading of
source-location entries would now end up opening those files. Worse,
those files wouldn't be closed until the file manager was destroyed,
so just opening a Cocoa.h PCH file would hold on to ~860 file
descriptors, and it was easy to blow through the process's limit on
the number of open file descriptors.

By eliminating the preloading of these files, we neither open nor stat
the headers stored in the PCH/AST file until they're actually needed
for something. Concretely, we went from

*** HeaderSearch Stats:
835 files tracked.
  364 #import/#pragma once files.
  823 included exactly once.
  6 max times a file is included.
  3 #include/#include_next/#import.
    0 #includes skipped due to the multi-include optimization.
1 framework lookups.
0 subframework lookups.

*** Source Manager Stats:
835 files mapped, 3 mem buffers mapped.
37460 SLocEntry's allocated, 11215575B of Sloc address space used.
62 bytes of files mapped, 0 files with line #'s computed.

with a trivial program that uses a chained PCH including a Cocoa PCH
to

*** HeaderSearch Stats:
4 files tracked.
  1 #import/#pragma once files.
  3 included exactly once.
  2 max times a file is included.
  3 #include/#include_next/#import.
    0 #includes skipped due to the multi-include optimization.
1 framework lookups.
0 subframework lookups.

Ted Kremenek 4bd19da586 Add hack to CMakeLists.txt so that StaticAnalyzer libraries find their corresponding headers.
This is a hack because we really should only search in the 'include/clang/StaticAnalyzer' directory
if we are in 'lib/StaticAnalyzer'.  My CMake knowledge is limited, so I appeal to anyone with
more expertise.
