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 a;

extern(C) int printf(char*, ...);

int i = 42;

void main()
{
    int j;
    j = i;
    int* p;
    p = &j;
    int k = *p;
    assert(k == 42);

    byte b = -1;
    int i = b;
    assert(i == -1);

    int* p2 = p;

    printf("Done\n");
}
