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 tangotests.asm4;

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

void main()
{
    char* stmt = "yay!\n";
    char* fmt = "%s";

    {
	asm
    	{
		jmp L2;
   	L1:;
		jmp L3;
    	L2:;
		jmp L1;
    	L3:;
		push stmt;
        	call printf;
        	pop EAX;
    	}
    }
    else version(LLVM_InlineAsm_X86_64)
