    lang/nim: fix on powerpc64
    
    countProcessors() reads the 4-byte hw.ncpu into an 8-byte int, which puts
    it in the high word on big-endian, so any nim c without --parallelBuild
    tried to size its build state for 2^38 CPUs and got OOM-killed. That is
    also why DOCS was turned off on powerpc64 in 2020, so enable it again.
    Also take the upstream fix for the shr constant folding on big-endian and
    apply it to the pre-generated bootstrap compiler too.

+The pre-generated bootstrap compiler reinterprets the first 8 bytes of an
+Int128 (an array of uint32 words, least significant first) as uint64 when
+folding shr, which only works on little-endian. Same fix as upstream
+e97b0bb541ee (castToUInt64) applied to the generated C.
