[PATCH 2/3] Add varobj zhexadecimal format tests.

[Luis Machado <lgustavo@codesourcery.com>]

This patch adds a few tests to exercise the new zhexadecimal format for
varobj's. I see 5 FAIL's without the zhexadecimal format support and full
passes with a zhexadecimal format support.

I renamed some of the tests to make them unique.

	* gdb.mi/mi-var-display.exp: Add new checks for the zhexadecimal format
	and change test names to make them unique.
