[PATCH v2 0/4] Fix s87_tw reconstruction to correctly indicate register states

[Michał Górny <mgorny%gentoo.org@localhost>]

Hi,

Here's the same as previously but with tests.  I have noticed that
the two relevant functions were in a separate file before, and I have
decided to revert the patch in order to separate them again (for tests).

The tests use similar approach as sys/netatalk tests, i.e. #include
the .c file containing utility functions in order to compile and test
them in userspace.

The first test issues series of FSAVE/FXSAVE calls for different test
vectors.  The result of each is converted to the other format,
and compared to the result of corresponding instruction.

The two next tests use fixed test data to populate appropriate structs,
and compare the result of conversion with known expected values.
