Move non-function-specific parts of libm-test.inc to separate file.

libm-test.inc contains both test infrastructure and tests of
individual functions.

This patch moves the infrastructure to a separate file
libm-test-driver.c.  This is in preparation for splitting the tests of
individual functions into separate source files, which will be
processed individually by gen-libm-test.pl (so e.g. libm-test-acos.inc
and auto-libm-test-out-acos will be processed by gen-libm-test.pl to
produce libm-test-acos.c, and files such as test-double-acos.c will be
generated by the Makefile to include appropriate headers,
libm-test-driver.c and libm-test-acos.c so tests of each function get
run separately).

It is no doubt possible to split things up further, so that functions
not depending on the type being tested only get compiled once and most
of those depending on the type being tested get compiled once per type
(rather than separately for variants such as inline / no-inline, and
separately for each function being tested after that split), but this
rearrangement as-is seems a useful incremental step towards splitting
these tests by function.

+/* "Philosophy":
+
+   This suite tests some aspects of the correct implementation of
+   mathematical functions in libm.  Some simple, specific parameters
+   are tested for correctness but there's no exhaustive
+   testing.  Handling of specific inputs (e.g. infinity, not-a-number)
+   is also tested.  Correct handling of exceptions is checked
+   against.  These implemented tests should check all cases that are
+   specified in ISO C99.
+
+   NaN values: The payload of NaNs is set in inputs for functions
+   where it is significant, and is examined in the outputs of some
+   functions.
+
+   Inline functions: Inlining functions should give an improvement in
+   speed - but not in precission.  The inlined functions return
+   reasonable values for a reasonable range of input values.  The
+   result is not necessarily correct for all values and exceptions are
+   not correctly raised in all cases.  Problematic input and return
+   values are infinity, not-a-number and minus zero.  This suite
+   therefore does not check these specific inputs and the exception
+   handling for inlined mathematical functions - just the "reasonable"
+   values are checked.
+
+   Beware: The tests might fail for any of the following reasons:
+   - Tests are wrong
+   - Functions are wrong
+   - Floating Point Unit not working properly
+   - Compiler has errors
+
+   With e.g. gcc 2.7.2.2 the test for cexp fails because of a compiler error.
+
+
+   To Do: All parameter should be numbers that can be represented as
+   exact floating point values.  Currently some values cannot be
+   represented exactly and therefore the result is not the expected
+   result.  For this we will use 36 digits so that numbers can be
+   represented exactly.  */
