Matt Arsenault d6511b49ac Add minnum / maxnum intrinsics 
These are named following the IEEE-754 names for these
functions, rather than the libm fmin / fmax to avoid
possible ambiguities. Some languages may implement something
resembling fmin / fmax which return NaN if either operand is
to propagate errors. These implement the IEEE-754 semantics
of returning the other operand if either is a NaN representing
missing data.

Matt Arsenault ee364ee729 Allow speculating llvm.sqrt, fma and fmuladd 
This doesn't set errno, so this should be OK.
Also update the documentation to explicitly state
that errno are not set.
