- Use "for_expression" rather than "allow_unknownanytype"
  to indicate that we're doing stuff for the expression
  parser.

- When for_expression is true, look through @s and find
  the actual class rather than just returning id. 

- Rename BuildObjCObjectType to BuildObjCObjectPointerType
  since it's actually returning an object *pointer* type.

- Fixed a bug where ::Describe for class descriptors
  would fail if the class had no ivars.

- Updated use of the RealizeType API by the class
  descriptors to use "for_expression" rather than
  the misnamed "allow_unknownanytype."

Updated the Objective-C runtime type vendor to
load ivars into classes that are reported to the
Objective-C runtime.

In ValueObjectDynamicValue, trust what comes from
the runtime rather than trying to fix it up,
because now those types have ivars regardless of
whether they come from "frame variable" or from
expressions.

commit on behalf of Oleksiy Vyalov Fix junk content handling within GDBRemoteCOmmunication::CheckForPacket  1. Avoid removing of an extra symbol from m_bytes.  2. iterate over m_bytes until useful content is found.  Differential Revision: http://reviews.llvm.org/D6042

SBAddress currently *may* have an Address object or it may not.
If it has an Address object, it is assumed to be Valid.
Change SBAddress to always have an Address object and check
whether it is valid or not in those case.

This is fixing a subtle problem where we ended up with
a SBAddress with an Address of LLDB_INVALID_ADDRESS could
run through a copy constructor and turn into an SBAddress
with no Address object being backed (because it wasn't
distinguishing between invalid-Address versus no-Address.)

The cost of an Address object is not high and this will be
an easy mistake for someone else to make; I'm fixing
SBAddress so it doesn't come up again.

Always transmit SIGPROF back to the inferior.

Summary:
SIGPROF is used for profiling processes (with google-perftools for
instance), which results in the inferior receiving a SIGPROF from the
kernel every few milliseconds. Instead of stopping the debugging session
and notifying the user of this, we should just pass the signal and keep
running.

This follows the behavior we have in UnixSignals.cpp.

Test Plan: Run LLDB on linux with a binary using google-perftools, see that execution gets interrupted all the time because we receive SIGPROF. Apply the patch, everything works fine.
