* configure.in: improve ICC (Intel C Compiler) support.
* configure.in (CXX): The name of icc's c++ compiler is `icpc`.
* configure.in (warnings): Add `-diag-disable=2259` to suppress
noisy warnings: "non-pointer conversion from "..." to "..." may
lose significant bits".
* configure.in (optflags): Add `-fp-model precise` like -fno-fast-math.
* lib/mkmf.rb: icc supports -Werror=division-by-zero
and -Werror=deprecated-declarations, but doesn't support
-Wdivision-by-zero and -Wdeprecated-declarations.
