[commit] Rename .C test files

[Daniel Jacobowitz <drow at false dot org>]

The use of .C files to mean C++ is a little sketchy on
case-insensitive file systems, and not related to the point of the
test.  I renamed them after a brush with the Symbian SDK, which
chooses which compiler to use based on the case-insensitive
file extension.

Tested on mips-linux-gnu, checked in.
