keep a shared pointer to their disassembler.  This
is important for the LLVM-C disassembler because
it needs to lock its parent in order to disassemble
itself.

This means that every interface that returned a
Disassembler* needs to return a DisassemblerSP, so
that the instructions and any external owners share
the same reference count on the object.  I changed
all clients to use this shared pointer, which also
plugged a few leaks.

Added new API to lldb::SBTypeMember for bitfields:

    bool SBTypeMember::IsBitfield();
    uint32_t SBTypeMember::GetBitfieldSizeInBits();

Also added new properties for easy access. Now SBTypeMember objects in python have a "fields" property for all type fields, "bases" for all direct bases, "vbases" for all virtual base classes and "members" for a combo of all three organized by bit offset. They all return a python list() of SBTypeMember objects. Usage:
(lldb) script
>>> t = lldb.target.FindFirstType("my_type")
>>> for field in t.fields:
...     print field
>>> for vbase in t.vbases:
...     print vbase
>>> for base in t.bases:
...     print base
>>> for member in t.members:
...     print member

Also added new "is_bitfield" property to the SBTypeMember objects that will return the result of SBTypeMember::IsBitfield(), and "bitfield_bit_size" which will return the result of SBTypeMember::GetBitfieldSizeInBits();

I also fixed "SBTypeMember::GetOffsetInBytes()" to return the correct byte offset.

instructions, be sure to allocate new UnwindPlan::Row's each
time we push a row on to the UnwindPlan so we don't mutate 
it any further.

(fallout from changing the UnwindPlan from having a vector
of Row's to having a vector of RowSP shared pointers.)

Convert from calling Halt in the lldb Driver.cpp's input reader's sigint handler to sending this AsyncInterrupt so it can be handled in the 
event loop.
If you are attaching and get an async interrupt, abort the attach attempt.
Also remember to destroy the process if get interrupted while attaching.
Getting this to work also required handing the eBroadcastBitInterrupt in a few more places in Process WaitForEvent & friends.

sel_getName() calls are generated for all Objective-C

etc when the process is still running and debug builds of lldb would
assert down in GDBRemoteRegisterContext.cpp ReadRegisterBytes because
we couldn't get the sequence mutex for talking to the remote system.
Non-debug builds would just silently fail when doing this.

Relax the test for "is the frame I am going to step back out to the one I started from" in ThreadPlanStepOverRange so you don't
artificially reject stepping out of a function you stepped into when stepping through an inlined range.  

Also fill in the target in the symbol context we make up for the inlined stepping range in ThreadPlanStepOut.

Cleaned up the lldb_private::Mangled class to get rid of the tokenizing code that has bit rotted and isn't being used. Also cleaned up the API to the "lldb_private::Mangled" to always take "const ConstString &" arguments instead of both "const ConstString &" and "const char *". 

llvm-svn: 160466

Improved the error message when we can find a function in the current program by printing the demangled name.

Also added the ability to create lldb_private::Mangled instances with a ConstString when we already have a ConstString for a mangled or demangled name. Also added the ability to call SetValue with a ConstString and also without a boolean to indicate if the string is mangled where we will now auto-detect if the string is mangled.
