Dodji Seketeli 2f88edd3b3 Fix synthesizing of pointer type 
Libabigail fails to to synthesize a non-existing pointer type to an
existing type.

This makes abicompat fail in weak mode when trying to detect changes
to a function type where the parameter is a pointer to a structure
which changed.  In the application, the function is invoked and a
pointer to the structure is passed to it.  It appears that the type of
structure is defined in the debug info of the application, but not the
pointer to that structure.  So abicompat needs to synthesize that
pointer to struct in order to synthesize the type of the function, and
so, compare it to the type of the function coming from the library.

It appears that synthesizing a pointer type (to an existing type) is
not supported.  Only synthesizing qualified type was supported.

This patch adds support for that and thus fixes the abicompat test
case that is attached.

	* include/abg-ir.h: Update copyright.
	* src/abg-ir.cc (synthesize_type_from_translation_unit): Support
	synthesizing pointer types.

	* tests/data/test-abicompat/libtest8-fn-changed-libapp-v0.so: New
	test input.
	* tests/data/test-abicompat/libtest8-fn-changed-libapp-v1.so: Likewise.

	* tests/data/test-abicompat/test8-fn-changed-report-0.txt: Likewise.
	* tests/data/Makefile.am: Add the new test input files to source
	distribution.
	* tests/test-abicompat.cc (in_out_specs): Add the new test inputs
	above to the test harness.
