Hi,
IPA-CP can currently handle addresses of scalar constants (CONST_DECL) so this
extends that to addresses of constants in the pool (DECL_IN_CONSTANT_POOL).
Again this is helpful for so-called fat pointers in Ada, i.e. objects that are
semantically pointers but represented by structures made up of two pointers.
This also moves the unused function print_ipcp_constant_value from ipa-cp.cc
to ipa-prop.cc and renames it.
I have an LTO testcase for which this makes a difference, but it's large so
not really suitable for the testsuite.
Bootstrapped/regtested on x86-64/Linux, OK for the mainline?

* ipa-cp.cc (print_ipcp_constant_value): Move to...
(values_equal_for_ipcp_p): Deal with VAR_DECLs from the
constant pool.
* ipa-prop.cc (ipa_print_constant_value): ...here. Likewise.
(ipa_print_node_jump_functions_for_edge): Call the function
ipa_print_constant_value to print IPA_JF_CONST elements.
OK
