In a module-enabled Cocoa PCH file, we spend a lot of time stat'ing the headers
in order to associate the FileEntries with their modules and support implicit
module import.

Use a more lazy scheme by enhancing HeaderInfoTable to store extra info about
the module that a header belongs to, and associate it with its module only when
there is a request for loading the header info for a particular file.

This allows resolving top-header filenames of modules to FileEntries when
we need them, not eagerly.

Note that that this breaks ABI for libclang functions
clang_Module_getTopLevelHeader / clang_Module_getNumTopLevelHeaders
but this is fine because they are experimental and not widely used yet.

- fix TestCPPBool (was failing with some versions of GCC due to num_breakpoint_locations)
- speed up tests by skipping git/svn revision parsing by the test harness when running in lit-compatible (parsable) mode

This should resolve the failures reported by http://lab.llvm.org:8011/builders/lldb-x86_64-linux

When BugReporter tracks C++ references involved in a null pointer violation, we
want to differentiate between a null reference and a reference to a null pointer. In the
first case, we want to track the region for the reference location; in the second, we want
to track the null pointer.

In addition, the core creates CXXTempObjectRegion to represent the location of the
C++ reference, so teach FindLastStoreBRVisitor about it.

This helps null pointer suppression to kick in.

(Patch by Anna and Jordan.)

Made the "--reverse" option to "source list" also be able to use the "--count". This helps us implement support for regexp source list command:

(lldb) l -10

Which gets turned into:

(lldb) source list --reverse --count 10

Also simplified the code that is used to track showing more source from the last file and line.

In r176898 I updated the cost model to reflect the fact that sext/zext/cast on
v8i32 <-> v8i8 and v16i32 <-> v16i8 are expensive.

This test case is so that we make sure to update the cost model once we fix
CodeGen.
