Recognize that MSVC can support strtoll() and strtoull().

tglsfdc · tglsfdc · commit 63d3e787f954 · 2018-05-18T12:52:28.000-04:00
This is needed for full support of "long long" variables in ecpg, but the previous patch for bug #15080 (commits 51057fe et al) missed it. In MSVC versions where the functions don't exist under those names, we can nonetheless use _strtoi64() and _strtoui64(). Like the previous patch, back-patch all the way.
