c++: Disable -Wint-in-bool-context in instantiations

This warning is of questionable value when it's emitted when
instantiating a template, as in the following testcase.  It could be
silenced by writing hb(i) << 1 instead of 2 * hb(i) but that's
unnecessary obfuscation.

gcc/cp/ChangeLog:

* pt.c (tsubst_copy_and_build): Add warn_int_in_bool_context
sentinel.

gcc/testsuite/ChangeLog:

* g++.dg/warn/Wint-in-bool-context-2.C: New test.
