MIR Parser: Move the parsing of fixed stack object indices into new method. NFC

This commit moves the code that parses the frame indices for the fixed stack
objects from the method 'parseFixedStackObjectOperand' to a new method named
'parseFixedStackFrameIndex', so that it can be reused when parsing fixed stack
pseudo source values.
