[NFC][compiler-rt] Factor out __mulv[sdt]i3 implementations to .inc file

Authored by atrosinenko on Aug 20 2020, 3:36 AM.



The existing implementations are almost identical except for width of the integer type.

Factor them out to for better maintainability.

The following command may help understanding the changes:

diff \
     <(git show master:./mulvsi3.c | sed 's/si_int/fixint_t/g')

The si and di variants has three lines different (with two of them being comments) and ti has a bit larger diff.

---*- C++ -*-===//

Explicitly mark .inc file as a C source like is already done for almost all * files.

Thanks. It really is a C source (there are no C++ sources in the builtins library, as far as I know), still almost all other .inc files in this directory are actually marked with -*- C -*-, so explicitly marked this one as well.

Interestingly, is the only one such file explicitly marked as C++, but it is probably a mistake.
