Greg Clayton fe42ac4d0a Cleaned up the SBType.h file to not include internal headers and reorganized
the SBType implementation classes.

Fixed LLDB core and the test suite to not use deprecated SBValue APIs.

Added a few new APIs to SBValue:

    int64_t
    SBValue::GetValueAsSigned(int64_t fail_value=0);

    uint64_t
    SBValue::GetValueAsUnsigned(uint64_t fail_value=0)

Jim Ingham b7f0bfc5dc Add a directory to make the second copy of libd.dylib in, so we don't have
to make & delete directories in the test case.  Make a real copy of libd.dylib
in that directory so the two libraries are actually different.  Use (and remove)
the DYLD_LIBRARY_PATH to point to the new library.

Sean Callanan a789aa770e Improved the expression parser's detection of the
current context.  Previously, if there was a variable
called "self" available, the expression parser
assumed it was inside a method.  But class methods
in Objective-C also take a "self" parameter, of DWARF
type "id".  We now detect this properly, and only
assume we're in an instance method if "self" is a
pointer to an Objective-C object.

Greg Clayton fad9eef23b Fixed an issue with parsing object files from .a archives.
The entire .a file gets cached, and after the first .o file
gets loaded, a cached version would get used when trying to
extract the skinny slice from a fat BSD archive and would
cause a code path to get taken in the BSD archive parser
even if we aren't at a BSD archive offset.

Greg Clayton d41f032a45 Fixed an issue where StackFrame::GetValueForVariableExpressionPath(...)
was previously using the entire frame variable list instead of using the
in scope variable list. I added a new function to a stack frame:

	lldb::VariableListSP
	StackFrame::GetInScopeVariableList (bool get_file_globals);

This gets only variables that are in scope and they will be ordered such
that the variables from the current scope are first.

Johnny Chen aaa82ff9ad Add the real benchmarks comparing lldb against gdb for repeated expression evaluations.
Modify lldbbench.py so that lldbtest.line_number() utility function is available to
BenchBase client as just line_number(), and modify lldbtest.py so that self.lldbExec
(the full path for the 'lldb' executable) is available to BenchBase client as well.

An example run of the test case on my MacBook Pro running Lion:

1: test_compare_lldb_to_gdb (TestRepeatedExprs.RepeatedExprsCase)
   Test repeated expressions with lldb vs. gdb. ... 
lldb_avg: 0.204339
gdb_avg: 0.205721

Sean Callanan 763d72a1fd Fixed a bug in which the DWARF reader did not distinguish
appropriately between C++ static methods and non-static
methods.  This bug made it impossible to call most static
methods, either because Clang did not recognize that a
method could be called without providing a "this"
parameter, or because Clang did not properly mangle the
name of the method when searching for it in the target.

Also added a testcase.

Enrico Granata c3e320a7a0 Fixed a bug where a variable could not be formatted in a summary if its datatype already had a custom format
Fixed a bug where Objective-C variables coming out of the expression parser could crash the Python synthetic providers:
 - expression parser output has a "frozen data" component, which is a byte-exact copy of the value (in host memory),
   if trying to read into memory based on the host address, LLDB would crash. we are now passing the correct (target)
   pointer to the Python code
Objective-C "id" variables are now formatted according to their dynamic type, if the -d option to frame variable is used:
 - Code based on the Objective-C 2.0 runtime is used to obtain this information without running code on the target

Stopwatch (self.swatch) within the BenchBase's setUp() instance method to be available
to all the child classes.

Use self.swatch to measure elapsed time in TestRepeatedExprs.py, which needs to be
modified later on to actually measure repeated expression evaluations within the
context of lldb as well as gdb.

Sean Callanan 7f3755b5ff Fixed a problem in the expression parser that
caused functions that were cast as part of the
call to have that cast ignored once their 
addresses were resolved.

Notably, in the case of objc_msgSend(), if
the function was cast from something returning
i8* to something returning i8, the expression
parser was discarding the cast as part of its
resolution.  This caused crashes later on.

Johnny Chen a74bb0ae6f Start refactoring lldbtest.TestBase so that it inherits from a newly created lldbtest.Base class,
while its API clients remain unchanged.  The new lldbtest.Base class is to capture common behaviors
when working with the test driver to accomplish things.  The clients of lldbtest.Base can be
lldb command line and api tests as well as other generic tests like a benchmark test.

Sean Callanan cc427fadec This change brings in the latest LLVM/Clang, and
completes the support in the LLDB expression parser
for incomplete types.  Clang now imports types
lazily, and we complete those types as necessary.

Changes include:

- ClangASTSource now supports three APIs which it
  passes to ClangExpressionDeclMap.  CompleteType
  completes a TagDecl or an ObjCInterfaceDecl when
  needed; FindExternalVisibleDecls finds named
  entities that are visible in the expression's
  scope; and FindExternalLexicalDecls performs a
  (potentially restricted) search for entities
  inside a lexical scope like a namespace.  These
  changes mean that entities in namespaces should
  work normally.

- The SymbolFileDWARF code for searching a context
  for a specific name is now more general, and can
  search arbitrary contexts.

- We are continuing to adapt our calls into LLVM
  from interfaces that take start and end iterators
  when accepting multiple items to interfaces that
  use ArrayRef.

- I have cleaned up some code, especially our use
  of namespaces.

This change is neutral for our testsuite and greatly
improves correctness for large programs (like Clang)
with complicated type systems.  It should also lay
the groundwork for improving the expression parser's
performance as we are lazier and lazier about
providing type information.
