Bruteforce - embedded, relaxed ulp requirements (#839)

Browse Source 
* Add embedded profile ULP requiremnts for relaxed tests.

* Fixed exp relaxed ULP for embedded.

* Added a utility function, getAllowedUlpError, for determining FP32 ULP.

* Collection of requested changes from PR.

Re-named float_embedded_relaxed_ulps -> relaxed_embedded_error.

Re-ordered Func struct members.
