Joseph Myers	3b2f60328e	Build most libm-test support code once per type. libm-test-driver.c contains various functions used in the course of libm testing, which are built as part of each test using this machinery. Currently, these functions get built for three tests for each type (e.g. test-float, test-ifloat, test-float-finite), plus the vector function tests. All these tests are huge and thus slow to build; the output of gen-libm-test.pl totals around 40 MB across all functions. To make the individual tests built from the Makefile smaller, it makes sense to split these tests up so the tests for each function are built separately (thus, three tests for each (function, type) pair, plus vector tests built only for functions that actually have vector versions). This improves parallelism and means that if tests fail, the summary of failed tests makes it more obvious where the problem might be without needing to look in the .out files to see which functions' tests failed (though architecture maintainers still need to keep libm-test-ulps up to date to avoid spurious failures of little interest). Simply including libm-test-driver.c as-is in such individual-function tests does not work because of unused static check_* functions (those functions only being used for the types of the outputs of the function under test). It also means the common code gets built over 1000 times instead of nine (plus vector tests). To avoid that issue, this patch splits out the bulk of the libm-test-driver.c code into a separate file libm-test-support.c (with a few functions made non-static). That separate file is built only once for each floating-point type (so at present three times, or twice on architectures with long double = double). Definitions needed in both libm-test-support.c and libm-test-driver.c go in libm-test-support.h (it's possible some of those are in fact only needed in one of the two files). libm-test-driver.c keeps definitions of a limited number of variables used to configure how libm-test-support.c behaves, various macros and structures needed by individual-function tests, and the main function. This move is also consistent in spirit with the move away from test-skeleton.c having all the test support code, to a small support/test-driver.c included in individual tests with most of the code built separately.

Use independent type literals in libm-test-support.c

* math/libm-test-support.c (check_ulp): Use LIT() around literal
	numbers.

Move INIT_ARCH_EXT call from libm-test-support to libm-test-driver.

libmvec tests involve calling INIT_ARCH_EXT during initialization then
CHECK_ARCH_EXT before testing each function to see if the processor
being used for testing supports the required instruction set
extensions.

After my refactoring of libm-test infrastructure, the INIT_ARCH_EXT
call is in libm-test-support.c, built only once per floating-point
type.  Now, in fact all definitions of this macro are empty, but given
that the definitions in sysdeps/x86_64/fpu/math-tests-arch.h are
conditional on REQUIRE_* macros defined in particular vector tests, it
seems more correct for the INIT_ARCH_EXT call to go instead in
libm-test-driver.c which gets built separately with those REQUIRE_*
macros properly defined.  This patch moves the call there.

Tested for x86_64 and x86.

	* math/libm-test-support.h: Do not include <math-tests-arch.h>
	here.
	* math/libm-test-support.c (libm_test_init): Do not call
	INIT_ARCH_EXT here.
	* math/libm-test-driver.c: Include <math-tests-arch.h>.

Build most libm-test support code once per type.

libm-test-driver.c contains various functions used in the course of
libm testing, which are built as part of each test using this
machinery.

Currently, these functions get built for three tests for each type
(e.g. test-float, test-ifloat, test-float-finite), plus the vector
function tests.  All these tests are huge and thus slow to build; the
output of gen-libm-test.pl totals around 40 MB across all functions.
To make the individual tests built from the Makefile smaller, it makes
sense to split these tests up so the tests for each function are built
separately (thus, three tests for each (function, type) pair, plus
vector tests built only for functions that actually have vector
versions).  This improves parallelism and means that if tests fail,
the summary of failed tests makes it more obvious where the problem
might be without needing to look in the .out files to see which
functions' tests failed (though architecture maintainers still need to
keep libm-test-ulps up to date to avoid spurious failures of little
interest).

Simply including libm-test-driver.c as-is in such individual-function
tests does not work because of unused static check_* functions (those
functions only being used for the types of the outputs of the function
under test).  It also means the common code gets built over 1000 times
instead of nine (plus vector tests).  To avoid that issue, this patch
splits out the bulk of the libm-test-driver.c code into a separate
file libm-test-support.c (with a few functions made non-static).  That
separate file is built only once for each floating-point type (so at
