    i386: Do not use %ecx DRAP for functions that use __builtin_eh_return
[PR104362]

    %ecx can't be used for both DRAP register and eh_return.  Adjust
find_drap_reg
    to choose %edi for functions that uses __builtin_eh_return to avoid the
assert
    in ix86_expand_epilogue that enforces this rule.
