Adjust how gen-auto-libm-tests handles before-rounding/after-rounding cases.

This patch changes gen-auto-libm-tests so that, when generating test
results that depend on whether the architecture has before-rounding or
after-rounding tininess detection, the :before-rounding or
:after-rounding conditions go on the exception / errno flags
generated, rather than generating two separate lines in
auto-libm-test-out for e.g. flt-32:before-rounding and
flt-32:after-rounding.

The rationale for this is as follows.  It would be desirable for
testing a libm function in all rounding modes to require just one
function and array in libm-test.inc, not four (or five), with the
array of test data including expected results for all rounding modes
rather than separate arrays for each rounding mode that also need to
repeat all the test inputs.  For gen-libm-test.pl to generate data for
such an array from auto-libm-test-out, it would be helpful if each
(format, test input) pair has exactly four lines in
auto-libm-test-out, one for each rounding mode, rather than some
rounding modes having just one line and some having two because the
exceptions depend on tininess detection.

Tested x86_64 and x86.

	* math/gen-auto-libm-tests.c: Update comment on output format.
	(output_for_one_input_case): Generate before-rounding and
	after-rounding information as conditions on output flags not
	floating-point format.
	* math/auto-libm-test-out: Regenerated.
	* math/gen-libm-test.pl (cond_value): New function.
	(or_cond_value): Use cond_value.
	(generate_testfile): Handle conditional exceptions.

    ... : flags".  rounding-mode is "tonearest", "towardzero", "upward"
    or "downward".  format is a name from the floating_point_formats
    array, possibly followed by a sequence of ":flag" for flags from
-   "long32", "long64", "before-rounding" and "after-rounding" (the
-   last two indicating tests where expectations for underflow
-   exceptions depend on how the architecture detects tininess).
-   Inputs and outputs are specified as hex floats with the required
-   suffix for the floating-point type, or plus_infty or minus_infty
-   for infinite expected results, or as integer constant expressions
