Translate _d_arraysetlengthT to template

[Vild]

dmd PR: dlang/dmd#10106

rt.array.capacity._d_arraysetlengthT will call the _d_arraysetlength{,iT} depending on if T is zero initialized, this logic used to be inside of dmd.

I'm trying to figure out why this check is necessary, but I haven't succeeded yet. It shouldn't be required, but this check is a successful workaround. Until I can figure it out, please use D_TypeInfo instead of D_BetterC. I think GDC does not support betterC, but instead has individual flags like -fno-rtti, -fno-exceptions, etc. Using the more specific version specifier should make this code more portable. The error message would also need to be updated e.g. "Cannot resize arrays if compiling without support for runtime type information."

Thanks, I will do the same changes on the other PRs.

timelimit: sending warning signal 15
posix.mak:395: recipe for target 'unittest/std/datetime/systime.run' failed
gmake: *** [unittest/std/datetime/systime.run] Error 143

I don't think this auto-tester error have anything to do with my changes.
