Sean Callanan 35e678c7e0 Don't allow the expression parser to magically 
look through 'self' at its ivars.  It produces
surprising results.

Sean Callanan 5e3bdbff3f Fixed the expression parser to handle cases where 
GetValueForVariableExpressionPath returns NULL and
doesn't set an error.

Jason Molenda 84843ed536 A << operation would be undefined for a bit-selecting 
function because of a '1u' making it a 32-bit value
when it really needed to be a 64-bit value.  Trivial to fix
once I figured out what was going on.

Jason Molenda 61e0a3ef1f Put #if 0 blocks around three sections of code that are intentionally 
unreachable so we don't get warnings about them.

Completely initialize a structure instead of leaving some of its fields
potentially indeterminate (although in reality they would all be set 
before use -- but the compiler warning doesn't know that).

Zachary Turner cb37ddda0d Remove some unnecessary headers from Host.cpp

Matthew Gardiner 6e7b0a088e Improve the handling of kalimba ELF file section type recognition. 
Recognise the SHT_NOBITS property in kalimba ELF, and determine this to be
of type zerofilled. Subsequently recognise this type to represent bytes
on the target's DATA address space, and therefore be sized accordingly.
