count-one-bits: port to MSC; support types wider than 64 bits
The ideas behind the MSC port are stolen from Emacs.
* lib/count-one-bits.c (popcount_support) [_MSC_VER]: New variable.
* lib/count-one-bits.h: Include limits.h, for CHAR_BIT.
Don't include verify.h: it's no longer needed, as types wider than
64 bits are now supported.
(COUNT_ONE_BITS_GENERIC): New macro.
(popcount_supported) [_MSC_VER]: New inline function.
(COUNT_ONE_BITS): Use it. New arg MSC_BUILTIN, for better
performance with MSC. All uses changed. Do not assume that TYPE
has at most 64 bits.
* modules/count-one-bits (Depends-on): Do not depend on 'verify'.
