These testcases jit-compile functions that return char, but
were erroneously calling them as if they returned int.
This led to errors for certain target configurations (e.g.
reading from %eax (32-bit) in the harness when only %al (8-bit)
had been written to in the jit-compiled function).
Regrtested on x86_64-pc-linux-gnu, and smoketested with
"-with-arch=haswell--with-cpu=haswell".
Committed to trunk as r257037.
