Implement Xtensa FP Option instructions and lowering of the base FP operations with tests. Implement UR registers parsing. Fix loading from constant pool callee, basic block, globaladdress and jumptable addresses. Also fixed potential memory leakage when several similar XtensaConstantPoolValue objects are created Fix lowering i32 immediate.
