This patch adds internal functions for simple FLT_FN built-in functions,
in cases where an associated optab already exists. Unlike some of the
built-in functions, these internal functions never set errno.
LDEXP is an odd-one out in that its second operand is an integer.
All the others operate on uniform types.
The patch also adds a function to query the internal function associated
with a built-in function (if any), and another to test whether a given
gcall could be replaced by a call to an internal function on the current
target (as long as the caller deals with errno appropriately).
Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.
OK to install?
Thanks,
Richard

recog.h? I don't see anything that would require recognition in this
patch. Is there something in a later patch that needs the recog.h header?
If you don't need recog.h, then drop it.
OK for the trunk.
