Accuracy of Mathematical Functions

[Paul Zimmermann]

       Hi,

we have updated our comparison with Newlib 4.2.0:

There is not much change with respect to 4.1.0, only
larger errors for expf, tgammaf and lgammaf, but this
is due to a bug in our testing program, which did not
report those values before.

New libraries are compared: LLVM and ROCm.
