[commit] Don't call deprecated_inside_entry_file from ...id_unwind()

[Andrew Cagney <ac131313 at redhat dot com>]

Hello,

Sometime ago, while developing the frame unwind code using the d10v, I 
added an innocent looking hack that stopped the d10v falling off the end 
of its stack:

-  /* This is meant to halt the backtrace at "_start".  Make sure we
-     don't halt it at a generic dummy frame.  */
-  if (func <= IMEM_START || inside_entry_file (func))
-    return;

That logic being lifed from even older frame chain code.

I then later fixed the underlying problem (inside_main_func was broken), 
but forgot to remove that hack.

Oops!

That innocent looking code as quitely spread to at least 4 other 
architectures (there was no comment saying "hey you don't need this").

Anyway, the attached patch removes all occurance of the hack.

committed,
Andrew

	deprecated_inside_entry_file.
	* m68hc11-tdep.c (m68hc11_frame_this_id): Ditto.
	* m32r-tdep.c (m32r_frame_this_id): Ditto.
