Duncan Sands fdfdbd091d Remove NoVendor and NoOS, added in commit 123990, from Triple. While it
may be useful to understand "none", this is not the place for it.  Tweak
the fix to Normalize while there: the fix added in 123990 works correctly,
but I like this way better.  Finally, now that Triple understands some
non-trivial environment values, teach the unittests about them.

Nick Lewycky a46c898314 Remove wasteful caching. This isn't needed for correctness because any function
that might have changed been affected by a merge elsewhere will have been
removed from the function set, and it isn't needed for performance because we
call grow() ahead of time to prevent reallocations.

Greg Clayton 4272cc7d4c Modified the PluginManager to be ready for loading plug-ins from a system
LLDB plugin directory and a user LLDB plugin directory. We currently still
need to work out at what layer the plug-ins will be, but at least we are 
prepared for plug-ins. Plug-ins will attempt to be loaded from the 
"/Developer/Library/PrivateFrameworks/LLDB.framework/Resources/Plugins" 
folder, and from the "~/Library/Application Support/LLDB/Plugins" folder on
MacOSX. Each plugin will be scanned for:

extern "C" bool LLDBPluginInitialize(void);
extern "C" void LLDBPluginTerminate(void);

If at least LLDBPluginInitialize is found, the plug-in will be loaded. The
LLDBPluginInitialize function returns a bool that indicates if the plug-in
should stay loaded or not (plug-ins might check the current OS, current
hardware, or anything else and determine they don't want to run on the current
host). The plug-in is uniqued by path and added to a static loaded plug-in
map. The plug-in scanning happens during "lldb_private::Initialize()" which
calls to the PluginManager::Initialize() function. Likewise with termination
lldb_private::Terminate() calls PluginManager::Terminate(). The paths for the
plug-in directories is fetched through new Host calls:

    bool Host::GetLLDBPath (ePathTypeLLDBSystemPlugins, dir_spec);
    bool Host::GetLLDBPath (ePathTypeLLDBUserPlugins, dir_spec);

This way linux and other systems can define their own appropriate locations
for plug-ins to be loaded.

To allow dynamic shared library loading, the Host layer has also been modified
to include shared library open, close and get symbol:

    static void *
    Host::DynamicLibraryOpen (const FileSpec &file_spec, 
                              Error &error);

    static Error
    Host::DynamicLibraryClose (void *dynamic_library_handle);

    static void *
    Host::DynamicLibraryGetSymbol (void *dynamic_library_handle, 
                                  const char *symbol_name, 
                                  Error &error);

lldb_private::FileSpec also has been modified to support directory enumeration
in an attempt to abstract the directory enumeration into one spot in the code.
The directory enumertion function is static and takes a callback:


    typedef enum EnumerateDirectoryResult
    {
        eEnumerateDirectoryResultNext,  // Enumerate next entry in the current directory
        eEnumerateDirectoryResultEnter, // Recurse into the current entry if it is a directory or symlink, or next if not
        eEnumerateDirectoryResultExit,  // Exit from the current directory at the current level.
        eEnumerateDirectoryResultQuit   // Stop directory enumerations at any level
    };

    typedef FileSpec::EnumerateDirectoryResult (*EnumerateDirectoryCallbackType) (void *baton,
                                                                                  FileSpec::FileType file_type,
                                                                                  const FileSpec &spec);

    static FileSpec::EnumerateDirectoryResult
    FileSpec::EnumerateDirectory (const char *dir_path,
                                  bool find_directories,
                                  bool find_files,
                                  bool find_other,
                                  EnumerateDirectoryCallbackType callback,
                                  void *callback_baton);

This allow clients to specify the directory to search, and specifies if only
files, directories or other (pipe, symlink, fifo, etc) files will cause the
callback to be called. The callback also gets to return with the action that
should be performed after this directory entry. eEnumerateDirectoryResultNext
specifies to continue enumerating through a directory with the next entry.
eEnumerateDirectoryResultEnter specifies to recurse down into a directory
entry, or if the file is not a directory or symlink/alias to a directory, then
just iterate to the next entry. eEnumerateDirectoryResultExit specifies to 
exit the current directory and skip any entries that might be remaining, yet
continue enumerating to the next entry in the parent directory. And finally
eEnumerateDirectoryResultQuit means to abort all directory enumerations at 
all levels.

Modified the Declaration class to not include column information currently
since we don't have any compilers that currently support column based 
declaration information. Columns support can be re-enabled with the
additions of a #define.

Added the ability to find an EmulateInstruction plug-in given a target triple
and optional plug-in name in the plug-in manager.

Fixed a few cases where opendir/readdir was being used, but yet not closedir
was being used. Soon these will be deprecated in favor of the new directory
enumeration call that was added to the FileSpec class.

Evan Cheng d42641c6b5 Given a pair of floating point load and store, if there are no other uses of
the load, then it may be legal to transform the load and store to integer
load and store of the same width.

This is done if the target specified the transformation as profitable. e.g.
On arm, this can transform:
vldr.32 s0, []
vstr.32 s0, []

to

ldr r12, []
str r12, []

Sean Callanan 0917d6e5d5 Added a new class, ASTDumper, that provides verbose
diagnostics of Clang AST classes for the purpose of
debugging the types LLDB produces for DWARF objects.

The ASTDumper is currently only used in log output
if you enable verbose mode in the expression log:

log enable -v lldb expr

Its output then appears in the log for external
variables used by the expr command.

Douglas Gregor b278aafbfb Allocate CodeCompletionString and all of its components in a
BumpPtrAllocator, rather than manually new/delete'ing them. This
optimization also allows us to avoid allocating memory for and copying
constant strings (e.g., "return", "class").

This also required embedding the priority and availability of results
within the code completion string, to avoid extra memory allocation
within libclang.

David Greene 433c6180ab [AVX] Implement EnforceSmallerThan for mixed int/fp type lists. This
makes type checking for extract_subvector and insert_subvector more
robust and will allow stricter typechecking of more patterns in the
future.

This change handles int and fp as disjoint sets so that it will
enforce integer types to be smaller than the largest integer type and
fp types to be smaller than the largest fp type.  There is no attempt
to check type sizes across the int/fp sets.

Ted Kremenek 5b4288440d Add temporary hack to -Wuninitialize to create a separate CFG (for C++ code) that doesn't include implicit dtors.
Implicit dtors confuse the ad hoc path-sensitivity of UninitializedValuesV2.cpp.  This isn't
the ideal solution, as it will directly impact compile time, but should significantly reduce
the noise of -Wuninitialized on some code bases.

This immediately "fixes" the false positive reported in PR 9063, although this
isn't the right fix in the long run.
