Fix buffer overflow when creating patches with long RPN expressions
...
The createpatch() function was using a fixed-size buffer. I've changed it
to be dynamically allocated. I saw that the RPN format used in patches is
slightly different from the one used internally in the assembler, so I
added a new member to the Expression struct to track the patch size.
I've also limited the RPN expression length to 1MB. I realized that the
patch RPN expression could potentially be longer than the internal RPN
expression, so the internal expression would need a limit smaller than
UINT32_MAX. I thought 1MB would be a reasonable limit.

Don't assign PC to macro symbols
...
Macros have nothing to do with the current PC, so this doesn't make any sense.
The value isn't ever used either.
