Patch for missing sinf, cosf, ...

Here's the stat:
Builtin cos and sin are expanded only when -ffast-math; from
gcc/builtins.c:expand_builtin:
case BUILT_IN_SIN:
case BUILT_IN_COS:
/* Treat these like sqrt, but only if the user asks for them. */
if (! flag_fast_math)
break;
case BUILT_IN_FSQRT:
target = expand_builtin_mathfn (exp, target, subtarget);
if (target)
ÃÂ return target;
break;
So we need out-of-line implementations of sin{f,l} and cos{f,l}.
__builtin_sqrt seems to generate a library call when the inline
expansion generates a NaN; so we need out-of-line sqrt{f,l}, too.
fabs doesn't seem to have these problems; that bit can be removed.
