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.

enum fields 
{ 
    FIELD1, 
    FIELD2 
} 
 
fields find_field(fields f) { 
    with(fields) { 
        switch(f) { 
        case FIELD1:  
	  return FIELD1;
        default: 
	  return FIELD2;
        } 
    } 
} 
 
void main() { 
  assert(find_field(fields.FIELD1) == fields.FIELD1);
  assert(find_field(fields.FIELD2) == fields.FIELD2);
}
