  -----------
  [Xtensa] Implement SEXT, NSA, MINMAX and Loop Xtensa Options. (#133818)

Implement basic support of the several simple Xtensa Options with 1-4
instructions for each option. The Sign Extend Option (SEXT). The NSA
Option. The Minimum/Maximum Integer 32-bit Option and Loop Option.
Fixed address operands, added OPERAND_PCREL to operands descriptions.
