fixed a few potential NULL-pointer derefs in ValueObject
we have a way to provide docstrings for properties we add to the SWIG layer - a few of these properties have a docstring already, more will come in future commits
added a new bunch of properties to SBData to make it more natural and Python-like to access the data they contain

 - This is a more reliable default, as it behaves better on failure and also
   ensures that we create *new* files (instead of reusing existing inodes). This
   is useful for other applications (like lldb) which want to cache inode's to
   know when a file has been rewritten.

Frontend: Don't automatically create missing directories when using temporary files with createOutputFile()
 - This would otherwise happen as a side effect of llvm::sys::fs::unique_file creating parent directories.

This is a preparation to adding an AST-based call graph to Analysis. The
existing call graph works with indexer entries. We might be able to
refactor it to use the AST based graph in the future.

(Minimal testing here as the only example that uses the API has been
completely broken, does not compile.)

Add logic to GDBRemoteRegisterContext class to be able to read/write a "composite" register
which has "primordial" registers as its constituents.  In particular, Read/WriteRegisterBytes()
now delegate to Get/SetPrimordialRegister() helper methods to read/write register contents.

Also modify RegisterValue class to be able to parse "register write" string value for the
NEON quadword registers which is displayed as a vector of uint8's.

Example:

(lldb) register write q0 "{0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x09 0x0a 0x0b 0x0c 0x0d 0x0e 0x0f 0x10}"
(lldb) register read q0
q0 = {0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x09 0x0a 0x0b 0x0c 0x0d 0x0e 0x0f 0x10}
(lldb) register read --format uint8_t[] s0
s0 = {0x01 0x02 0x03 0x04}
(lldb) register read --format uint8_t[] d0
d0 = {0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08}
(lldb) register read --format uint8_t[] d1
d1 = {0x09 0x0a 0x0b 0x0c 0x0d 0x0e 0x0f 0x10}
