    Compile gdb.perf/skip-prologue.c with and without debug info
    
    gdb.perf/skip-prologue.exp is intended to measure the performance of
    skipping prologue with prologue analysis by setting breakpoints.
    However, if program is compiled with debug info, GDB is smart to
    skip prologue by line table from debug info, so prologue analysis
    is not exercised at all.
    
    This patch adds a parameter COMPILE to specify compiling with
    debug information, otherwise, it is compiled without debug
    information.
