Add libm-test support for per-rounding-mode manually specified results.
This patch continues the libm-test move towards automatic testing of
all test inputs in all rounding modes by adding gen-libm-test.pl
support for tests specifying results in each rounding mode manually.
Previously a TEST_* line could specify arguments and results, or
arguments, results and flags. Now there is the option of (arguments,
results-rd, flags-rd, results-rn, flags-rn, results-rz, flags-rz,
results-ru, flags-ru). This is used to replace the separate arrays of
results in each rounding mode for lrint, llrint and rint. (In the
case of rint, some tests were only in rint_test_data and needed to
have expectations for non-default rounding modes added, which I did
manually. In various cases there were slight differences in things
such as the ordering of tests in the arrays for each mode.)
Tested x86_64 and x86.
* math/gen-libm-test.pl (parse_args): Handle results specified for
each rounding mode separately.
* math/libm-test.inc (lrint_test_data): Merge in per-rounding-mode
tests and results from lrint_tonearest_test_data,
lrint_towardzero_test_data, lrint_downward_test_data and
lrint_upward_test_data.
(lrint_test): Use ALL_RM_TEST.
(lrint_tonearest_test_data): Remove.
(lrint_test_tonearest): Likewise.
(lrint_towardzero_test_data): Likewise.
(lrint_test_towardzero): Likewise.
(lrint_downward_test_data): Likewise.
(lrint_test_downward): Likewise.
(lrint_upward_test_data): Likewise.
(lrint_test_upward): Likewise.
(llrint_test_data): Merge in per-rounding-mode tests and results
from llrint_tonearest_test_data, llrint_towardzero_test_data,
llrint_downward_test_data and llrint_upward_test_data.
(llrint_test): Use ALL_RM_TEST.
(llrint_tonearest_test_data): Remove.
(llrint_test_tonearest): Likewise.
(llrint_towardzero_test_data): Likewise.
(llrint_test_towardzero): Likewise.
(llrint_downward_test_data): Likewise.
(llrint_test_downward): Likewise.
(llrint_upward_test_data): Likewise.
(llrint_test_upward): Likewise.
(rint_test_data): Merge in per-rounding-mode tests and results
from rint_tonearest_test_data, rint_towardzero_test_data,
rint_downward_test_data and rint_upward_test_data. Add
per-rounding-mode results for tests not in those arrays.
(rint_test): Use ALL_RM_TEST.
(rint_tonearest_test_data): Remove.
(rint_test_tonearest): Likewise.
(rint_towardzero_test_data): Likewise.
(rint_test_towardzero): Likewise.

(rint_test_upward): Likewise.
(main): Don't call removed functions.
