Dodji Seketeli 4ac6a09664 ir: Don't strip typedefs when comparing pointers & references 
Now that comparison potentially involving a canonicalized type is
always done using the canonicalized type even if the other type being
compared is not canonicalized, it turns out we don't need to strip
typedefs when comparing pointer and reference types.

This essentially undoes what the was done by the patch below:

	ir: Strip typedefs from pointed-to-types during comparison

	When comparing two pointers, a pointer to type T is considered
	different from a pointer to typedef-of-T.  This can lead to spurious
	self-comparison errors and doesn't provide any practical benefit.
	More-over, the hash value of type typedef-of-T is the same as the hash
	value of type T.  So today, a pointer to type T and pointer to
	typedef-of-T have the same hash value.

	This patch strips typedefs from the pointed-to type of pointers and
	references before comparing them.  It thus fixes the self-comparison
	issue exhibited by the command:

	    $ fedabipkgdiff --self-compare -a --from fc36 binutils

	* src/abg-ir.cc (equals): In the overload for pointer_type_def and
	reference_type_def, do not peel typedefs from the pointed-to types
	before comparing them.

README 

This is the Application Binary Interface Generic Analysis and
Instrumentation Library.

It aims at constructing, manipulating, serializing and de-serializing
ABI-relevant artifacts.

The set of artifacts that we are intersted is made of quantities like
types, variable, functions and declarations of a given library or
program.  For a given library or program this set of quantities is
called an ABI corpus.

This library aims at (among other things) providing a way to compare
two ABI Corpora (apparently the plural of corpus is copora, heh,
that's cool), provide detailed information about their differences,
and help build tools to infer interesting conclusions about these
differences.
