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 arrays8;

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

void main()
{
    char[] a = "hello ";
    printf("  \"%s\".length = %u\n", a.ptr, a.length);
    char[] b = "world";
    printf("  \"%s\".length = %u\n", b.ptr, b.length);
    char[] c = a ~ b;
    printf("After 'a ~ b':\n");
    printf("  \"%.*s\".length = %u\n", a.length, a.ptr, a.length);
    printf("  \"%.*s\".length = %u\n", b.length, b.ptr, b.length);
    printf("  \"%.*s\".length = %u\n", c.length, c.ptr, c.length);
    assert(c.length == a.length + b.length);
    assert(c !is a);
    assert(c !is b);
