Hello!

This patch implements lrint and llrint functions as built-in intrinsic 
functions. Attached to this message is only a middle-end part. In a 
followup message,  an x87 implementation will be attached.

This patch was bootstrapped and regtested (together with x87 
implementation) on i686-pc-linux-gnu, c and c++. A testcase that checks 
new built-ins is also implemented.

OK for mainline?

    * optabs.h (enum optab_index): Add new OTI_lrint and OTI_llrint.
    (lrint_optab, llrint_optab): Define corresponding macros.
    * optabs.c (init_optabs): Initialize lrint_optab and llrint_optab.
    * genopinit.c (optabs): Implement lrint_optab using lrintsi2
    pattern and llrint_optab using llrintdi2 patterns.
    * builtins.c (expand_builtin_mathfn): Handle BUILT_IN_LRINT{,F,L}
    using lrint_optab and BUILT_IN_LLRINT{,F,L} using llrint_optab.
    (expand_builtin): Expand BUILT_IN_LRINT{,F,L} and
    BUILT_IN_LLRINT{,F,L} using expand_builtin_mathfn if
    flag_unsafe_math_optimizations is set.

testsuite:

    * gcc.dg/builtins-46.c: Also check lrint* and llrint*.

Uros.
