    profiler: Don't include alloca.h when disabled
    
    alloca is a non-standard feature. It is possible for a system to put it
    in a different header, so including alloca.h unconditionally may cause
    compilation error. Since we only need alloca when this Linux-only
    profiler is enabled, we can simply move the include to the ifdef block.
