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 aa6;

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

void main()
{
    int[int] aa;
    aa = [1:1, 2:4, 3:9, 4:16];
    printf("---\n");
    foreach(int k, int v; aa)
        printf("aa[%d] = %d\n", k, v);
    aa.rehash;
    printf("---\n");
    foreach(int k, int v; aa)
        printf("aa[%d] = %d\n", k, v);
    size_t n = aa.length;
    assert(n == 4);
    int[] keys = aa.keys;
    assert(keys[] == [1,2,3,4][]);
    int[] vals = aa.values;
    assert(vals[] == [1,4,9,16][]);
    aa.remove(3);
    printf("---\n");
    foreach(int k, int v; aa)
        printf("aa[%d] = %d\n", k, v);
    assert(aa.length == 3);
}
