Rework gen-libm-test.pl input/output handling.
This patch reworks how input and output files are specified for gen-libm-test.pl. Previously, the script had names of various inputs and outputs hardcoded, with a -o option to specify an output directory. This patch replaces this with all inputs and outputs being specified explicitly as the arguments of options passed to the script. Outputs are only generated if the relevant option is passed, and only the processing required for the indicated outputs is done. The Makefile is made to pass options for generating libm-test-ulps.h in a separate invocation of gen-libm-test.pl from that generating libm-test.c. This is all in preparation for splitting up libm-test.inc and auto-libm-test-out and running tests separately for each function, when gen-libm-test.pl will be run separately for each function to generate the .c file but only once to generate libm-test-ulps.h (and those runs will be able to be in parallel). Tested for x86_64. The generated libm-test.c and libm-test-ulps.h are identical before and after the patch. Also tested the "make regen-ulps" case. * math/gen-libm-test.pl ($output_dir): Remove variable. ($srcdir): Likewise. ($opt_a): New variable. ($opt_c): Likewise. ($opt_C): Likewise. ($opt_H): Likewise. (-n): Make option take argument and use it as NewUlps output. (-a): New option. Use its argument for auto-libm-test-out input. (-c): New option. Use its argument for libm-test.inc input. (-C): New option. Use its argument for libm-test.c output. (-H): New option. Use its argument for libm-test-ulps.h output. (top level): Only process inputs needed to generate outputs specified by command-line options. Only generate outputs specified by command-line options. * math/README.libm-test: Update example gen-libm-test.pl command. * math/Makefile ($(objpfx)libm-test.stmp): Update gen-libm-test.pl commands. (regen-ulps): Likewise.
