4e62951282 Let's see if we can break things. 
Lower GOT relative addresses to Lo and HI.
Update both ISels to select them when they can.
Saves instructions here and there.

171049d10f * Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead. 
* Added a pseudo instruction (for each target) that represent "return void".
  This is a workaround for lack of optional flag operand (return void is not
  lowered so it does not have a flag operand.)

7b05bd5814 * Support for hasInFlag and hasOutFlag (on instructions). Remove nameless FLAG

c4769bb529 implement vastart. The dag isel compiles this: 
void test3(va_list Y);
void test2(int F, ...) {
  va_list X;
  va_start(X, F);
  test3(X);
}

into this:

test2:
        save -104, %o6, %o6
        st %i5, [%i6+88]
        st %i4, [%i6+84]

        call test3
        nop
        restore %g0, %g0, %g0
        retl

c4bb052ecc For PR351: 
Generally, remove use of fork/exec from bugpoint in favor of the portable
sys::Program::ExecuteAndWait method. This change requires two new options
to bugpoint to tell it that it is running in "child" mode. In this mode,
it reads its input and runs the passes. The result code signals to the
parent instance of bugpoint what happened (success, fail, crash).

This change should make bugpoint usable on Win32 systems.

64aa0ea4e9 this is a hack, which may or may not hang around. In short: 
whimper out of doing things the Right Way, and hack up a generic
'BRCALL' instruction, that gets generated when calls are lowered.
This gets selected by hand in the DAG isel, where it gets turned
into real (i.e. in tablegen) br.call instructions.

BUG: this dies on void calls, but seems to work otherwise?

BUG: calling printf(string, float) will load the float into the wrong
register, completely forget about loading the string, etce
