Implemented proper support for naked asm using llvm module level asm. Still not 100% complete, but already 1000 times better that what we had before. Don's BignumX86 implementation from Tango (when turned into a standalone unittest) seems to fully work with no changes, and great performance :) Fixed align N; in asm blocks. Fixed inreg parameter passing on x86 for ref/out params. Removed support for lazy initialization of function local static variables, I have no idea why I ever implemented this, it's not in the D spec, and DMD doesn't support it :P Some of the global variable related changes might cause minor regressions, but they should be easily fixable.

module aa4;

void main()
{
    int[int] aa;
    aa = addkey(aa,42,12);
    int* p = haskey(aa,42);
    assert(p && *p == 12);
}

int[int] addkey(int[int] aa, int key, int val)
{
    aa[key] = val;
    return aa;
}

int* haskey(int[int] aa, int key)
{
    return key in aa;
}
