Oops, I must have built a testcase for transparent regparamization with -O0
or something.  Can't reproduce it any longer.

But in that case gdb inferior calls argument shouldn't be something
that prevents this optimization, as you already can't call such functions
in inferior with stock gcc, so the patch doesn't make it any worse.
