Meador Inge 780a1861f1 Add more functions to the target library information. 
I discovered a few more missing functions while migrating optimizations
from the simplify-libcalls pass to the instcombine (I already added some
in r167659).

Meador Inge 03be256db9 instcombine: Query target library information to gate libcall simplifications 
Several of the simplifiers migrated from the simplify-libcalls pass to
the instcombine pass were not correctly checking the target library
information to gate the simplifications.  This patch ensures that the
check is made.
