[PATCH 1/4] Remove the error handling wrapper from exp and exp2

[Joseph Myers]

These four patches are OK.

To confirm, since you didn't mention it in the commit message: whenever 
the ieee754/dbl-64 implementations with integrated error handling are 
used, the *f32x and *f64 names point directly to those after these 
patches, not to any wrappers, since those names never supported SVID error 
handling (were deliberately only added as aliases after _LIB_VERSION and 
matherr were made into compat symbols).
