Fixed Temporary issues

Some issues, like failures using the do-while command, were caused
by the assembler being unable to assign registers consistently for
a single temporary variable. For example, in the do-while case, the
"iterate" Temporary object was not being assigned to the same
register between it's initial declaration and it's usage inside the
loop condition later on, causing the do-while to behave weirdly.
Other instances where multiple Temporary objects ended up being used
simultaneously of where a single object was references in multiple
parts of the code could have failed because of this.

The fix is simply to assign Temporary objects a unique ID.
