init and compare opcode hashmap with uppercase symbols

This is necessary now there are TableRef items like #All that need to be
matched case insensitive but displayed preserving the case as coded /
translated.

As a side effect, OOXML functions with _xlfn. prefix are now matched in
case that prefix was uppercase.
