[Pixman] [PATCH 5/7] a1-trap-test: Add tests for operator_name and format_name()

[Søren Sandmann]

From: Søren Sandmann Pedersen <ssp at redhat.com>

The check-formats.c test depends on the exact format of the strings
returned from these functions, so add a test here.

a1-trap-test isn't the ideal place, but it seems like overkill to add
a new test just for these trivial checks.
