semantics after the C++0x is_convertible type trait. This
implementation is not 100% complete, because it allows access errors
to be hard errors (rather than just evaluating false).

llvm-config --cflags --cxxflags --cppflags
We shouldn't impose those flags on people who use llvm-config for
building their own projects.

FileManager.cpp: Allow virtual files in nonexistent directories.
FileManager.cpp: Close FileDescriptor for virtual files that correspond to actual files.
FileManager.cpp: Enable virtual files to be created even for files that were flagged as NON_EXISTENT_FILE, e.g. by a prior (unsuccessful) addFile().
ASTReader.cpp: Read a PCH even if the original source files cannot be found.
Add a test for reading a PCH of a file that has been removed and diagnostics referencing that file.

deallocation function has a two-argument form. Store the result of this
check in new[] and delete[] nodes.

sessions: When continue packet has been sent and an interrupt packet was
quickly sent, it would get read at the same time:
$c#00\x03
There was an error where the packet end index was always being computed
incorrectly by debugserver, but it wouldn't matter if there weren't extra
bytes on the end (the hex \x03 interrupt byte in this case). The first
'$' last 3 bytes of the data in the packet buffer were being trimmed
(trying to trim the '#' + checksum (#XX)) which made:
c#
And this would then be passed to the handle routine for the 'c' packet which
would see an extra character at the end and assume it was going to be in the
form c[addr] where "[addr]" was a hex address to resume at and this would
result in a malformed packet response. This is now fixed and everything works
great.
Another issue was issuing async packets correctly by doing correct handshakes
between the thread that wants to send the async packet, and the thread that
is tracking the current run.
Added a write lock to the communication class as well to make sure you never
get two threads trying to write data at the same time. This wasn't happening,
but it is a good idea to make sure it doesn't.

Linear scan regalloc is currently assuming that any register aliased with
a member of a regclass must also be in at least one regclass. That is not
always true. For example, for X86, RIP is in a regclass but IP is not.
If you're unlucky, this can cause a crash by invalidating the iterator.

lldb_private::Function objects. Previously the SymbolFileSymtab subclass
would return lldb_private::Symbol objects when it was asked to find functions.
The Module::FindFunctions (...) now take a boolean "bool include_symbols" so
that the module can track down functions and symbols, yet functions are found
by the SymbolFile plug-ins (through the SymbolVendor class), and symbols are
gotten through the ObjectFile plug-ins.
Fixed and issue where the DWARF parser might run into incomplete class member
function defintions which would make clang mad when we tried to make certain
member functions with invalid number of parameters (such as an operator=
operator that had no parameters). Now we just avoid and don't complete these
incomplete functions.
