More Visual C related stuff.
compiler/globals.m:
Allow the C compiler type string for Visual C to have the form
"msvc_<VERSION>" as well as "cl_<VERSION>". Support for the
latter form will eventually be dropped.
configure.in:
Avoid pattern matching on the value of CC; it isn't a reliable
way of telling what the C compiler is.
Use the "-" form of options for MSVC in more places.
scripts/ml.in:
Use the "-" form of options for MSVC.
