Siva Chandra Reddy 3f4674a557 [libc] Extend MPFRMatcher to handle multiple-input-multiple-output functions. 
Tests for frexp[f|l] now use the new capability. Not all input-output
combinations have been addressed by this change. Support for newer combinations
can be added in future as needed.

Siva Chandra Reddy fbaaa16802 [libc] Add no_sanitize("address") attribute to the getMPFRMatcher function. 
This dramtically reduces the run time of tests. For example,
sincosf_test takes over 25 minutes without this attribute but only 8
seconds with this attribute.

Siva Chandra Reddy d69cbd826a [libc] Improve information printed on failure of a math test which uses MPFR. 
A new test matcher class MPFRMatcher is added along with helper macros
EXPECT|ASSERT_MPFR_MATCH.

New type traits classes RemoveCV and IsFloatingPointType have been
added and used to implement the above class and its helpers.

Siva Chandra Reddy 5fedf7f420 [libc] Move implementations of cosf, sinf, sincosf to src/math directory. 
NFC intended in the implementaton. Only mechanical changes to fit the LLVM
libc implementation standard have been done.

Math testing infrastructure has been added. This infrastructure compares the
results produced by the libc with the high precision results from MPFR.
Tests making use of this infrastructure have been added for cosf, sinf and
sincosf.
