MIR Parser: Extract the parsing of the operand's offset into a new method. NFC.

Browse Source 
This commit extract the code that parses the 64-bit offset from the method
'parseOperandsOffset' to a new method 'parseOffset' so that we can reuse it
when parsing the offset for the machine memory operands.
