Automatically check sanity of ulps from libm tests.
This patch makes libm-test.inc apply sanity checks to ulps values resulting from tests, or found in libm-test-ulps files, to avoid the need for manual checking/editing of new ulps for cases that are excessively large or involve functions that should not have any ulps. For IBM long double, errors must be at most 14ulp (the largest currently checked-in value), or at most 3ulp (the documented error bound for division) in the case of exactly-determined functions; for other formats, the limits are 9ulp (also the largest currently checked-in value) and 0ulp. Limits from ulps files are saturated to those bounds, and regen-ulps will ignore any errors outside those bounds. (Thus if, say, you have an architecture-specific problem with fma, the tests can still be XFAILed in auto-libm-test-in, but errors outside the permitted range can no longer be listed in libm-test-ulps.) Tested x86_64. * math/libm-test.inc (max_valid_error): New variable. (init_max_error): Take new argument specifying whether function results are exactly determined. Set max_valid_error and bound other variables for errors based on this argument. (set_max_error): Do not record results above max_valid_error. (check_float_internal): Only accept errors of up to 0.5ulps if also at most max_valid_error. (START): Take new argument EXACT and pass it to init_max_error. (acos_test): Update call to START.
