optimize u128/i128 popcounts further 
Don't fall back on breaking apart the popcount operation if 128-bit
integers are natively supported.

optimize popcount implementation

optimize popcount implementation 
In the current implementation, the gcc backend of rustc currently emits the
following for a function that implements popcount for a u32 (x86_64 targeting
AVX2, using standard unix calling convention):

    popcount:
        mov     eax, edi
        and     edi, 1431655765
        shr     eax
        and     eax, 1431655765
        add     edi, eax
        mov     edx, edi
        and     edi, 858993459
        shr     edx, 2
        and     edx, 858993459
        add     edx, edi
        mov     eax, edx
        and     edx, 252645135
        shr     eax, 4
        and     eax, 252645135
        add     eax, edx
        mov     edx, eax
        and     eax, 16711935
        shr     edx, 8
        and     edx, 16711935
        add     edx, eax
        movzx   eax, dx
        shr     edx, 16
        add     eax, edx
        ret

Rather than using this implementation, gcc could be told to use Wenger's
algorithm.  This would give the same function the following implementation:

    popcount:
        xor eax, eax
        xor edx, edx
        popcnt eax, edi
        test edi, edi
        cmove eax, edx
        ret

This patch implements the popcount operation in terms of Wenger's algorithm in
all cases.

e1cb8187e1 docs: add Rust logo to more compiler crates 
c6e6ecb1afea9695a42d0f148ce153536b279eb5 added it to some of the
compiler's crates, but avoided adding it to all of them to reduce
bit-rot. This commit adds to more.

d7766ffa36 treat host effect params as erased generics in codegen 
This fixes the changes brought to codegen tests when effect params are
added to libcore, by not attempting to monomorphize functions that get
the host param by being `const fn`.
