Avoid a deadlock when using the OperatingSystemPython code and typing "process interrupt". There was a possible lock inversion between the target API lock and the process' thread list lock due to code trying to discard the thread list. This was fixed by adding a boolean to Process::Halt() that indicates if the thread plans should be discarded and doing it in the private state thread when we process the stopped state.

mips16/mips32 floating point interoperability. 

This patch fixes returns from mips16 functions so that if the function
was in fact called by a mips32 hard float routine, then values
that would have been returned in floating point registers are so returned.

Mips16 mode has no floating point instructions so there is no way to
load values into floating point registers.

This is needed when returning float, double, single complex, double complex
in the Mips ABI.

Helper functions in libc for mips16 are available to do this.

For efficiency purposes, these helper functions have a different calling
convention from normal Mips calls.

Registers v0,v1,a0,a1 are used to pass parameters instead of
a0,a1,a2,a3.

This is because v0,v1,a0,a1 are the natural registers used to return
floating point values in soft float. These values can then be moved
to the appropriate floating point registers with no extra cost.

The only register that is modified is ra in this call.

The helper functions make sure that the return values are in the floating
point registers that they would be in if soft float was not in effect
(which it is for mips16, though the soft float is implemented using a mips32
library that uses hard float).

Previously, BitstreamCursor read an abbreviated record by splatting the
whole thing into a data vector, then extracting and removing the /first/
element. Now, it reads the first element--the record code--separately from
the actual field values.

* Provide DW_TAG_template_value_parameter for pointers, function
  pointers, member pointers, and member function pointers (still missing
  support for template template parameters which GCC encodes as a
  DW_TAG_GNU_template_template_param)
* Provide values for all but the (member & non-member) function pointer case.
  Simple constant integer values for member pointers (offset within the
  object) and address for the value pointer case. GCC doesn't provide a
  value for the member function pointer case so I'm not sure how, if at
  all, GDB supports encoding that. & non-member function pointers should
  follow shortly in a subsequent patch.
* Null pointer value encodings of all of these types, including
  correctly encoding null data member pointers as -1.

<rdar://problem/13594769>

Main changes in this patch include:
- cleanup plug-in interface and use ConstStrings for plug-in names
- Modfiied the BSD Archive plug-in to be able to pick out the correct .o file when .a files contain multiple .o files with the same name by using the timestamp
- Modified SymbolFileDWARFDebugMap to properly verify the timestamp on .o files it loads to ensure we don't load updated .o files and cause problems when debugging

The plug-in interface changes:

Modified the lldb_private::PluginInterface class that all plug-ins inherit from:

Changed:

virtual const char * GetPluginName() = 0;

To: 

virtual ConstString GetPluginName() = 0;

Removed:

virtual const char * GetShortPluginName() = 0;

- Fixed up all plug-in to adhere to the new interface and to return lldb_private::ConstString values for the plug-in names. 
- Fixed all plug-ins to return simple names with no prefixes. Some plug-ins had prefixes and most ones didn't, so now they all don't have prefixed names, just simple names like "linux", "gdb-remote", etc.

The issue was that the MatchingInlineAsm and VariantID args to the
MatchInstructionImpl function weren't being set properly.  Specifically, when
parsing intel syntax, the parser thought it was parsing inline assembly in the
at&t dialect; that will never be the case.  

The crash was caused when the emitter tried to emit the instruction, but the
operands weren't set.  When parsing inline assembly we only set the opcode, not
the operands, which is used to lookup the instruction descriptor.

Also, this commit reverts r176036.  Now that we're correctly parsing the intel
syntax the pushad/popad don't match properly.  I've reimplemented that fix using
a MnemonicAlias.
