* src/parse-gram.y: Define PERCENT_EXPECT_RR.

(declaration): Replace expected_conflicts with expected_sr_conflicts.
Add %expect-rr rule.

* src/scan-gram.l: Recognize %expect-rr.

* src/conflicts.h (expected_sr_conflicts): Rename from
expected_conflicts.
(expected_rr_conflicts): Declare.

* src/conflicts.c (expected_sr_conflicts): Rename from
expected_conflicts.
(expected_rr_conflicts): Define.
(conflicts_print): Check r/r conflicts against expected_rr_conflicts
for GLR parsers.
Use expected_sr_conflicts in place of expected_conflicts.
Warn if expected_rr_conflicts used in non-GLR parser.

* doc/bison.texinfo: Add documentation for %expect-rr.
