Add expm1 test case to cover the k==1024 case (#4508)
-7.095e+02 won't trigger the  k==1024 case, so we didn't add it into the test list

Get isfinite, isinf, and isnan right in jerry-math (#4497)
- `finite` is not C99 but a BSD fp classification function, so it
  is removed.
- The standard specifies that `isnan` is a macro (just like
  `isfinite` and `isinf`), so the `isnan` function implementation
  is removed.
- `isfinite` incorrectly classified NAN as finite, which is fixed.
- `isinf` returned 1 for negative infinity. This is not a bug
  according to the standard, but is not aligned with recent glibc,
  which returns -1. This is changed to simplify testing.
- Added test cases for `isfinite` and `isinf` to the unit test of
  jerry-math.
- Added a new pass to unittests to ensure that jerry-math is
  tested.

Rename jerry-libm to jerry-math (#4410)
That "libm" in the name of the library resulted in awkward naming
on *nix systems (`libjerry-libm.*`, "lib" occurring twice). And the
name of the corresponding header is `math.h` anyway.

Note that this is a breaking change in some sense. The commit
contains no API change, but the build system does change for users
of the math library.
