Attached to this message, please find updated patch and testcase for 
log10 and log2 builtins.

BTW: I think that testing log10 and log2 functions with compile-time 
constants is not necessary. In the
future, perhaps some -ffast-math optimization pass could replace 
functions with constant arguments with
their calculated value.
