    [Committed] PR testsuite/105486: Use "signed char" in gcc.dg/pr102950.c
    
    Although the automated regression testing scripts for powerpc64 appear
    to be somewhat garbled at the moment, they've correctly identified that
    my new test case for pr102950.c is failing on powerpc64, as char by
    default is unsigned on this target.  This patch tweaks the new testcase
    by explicitly using "signed char" so that it's testing the intended EVRP
    behaviour portably.  Committed as obvious.
