In ARC assembler, we accept case insensitive mnemonics, but this was
not the case for extension instruction, fix it and add a test.

* config/tc-arc.c (tokenize_extinsn): Convert to lower case the
name of extension instructions.
* testsuite/gas/arc/textinsn_case.d: New file.
* testsuite/gas/arc/textinsn_case.s: Likewise.
