Chris Lattner d3d086d679 consolidate LinkLibraries into LinkItems

Chris Lattner f901355379 make sure to mark nodes in the globals graph incomplete after computing it 
so that external globals (and whatever they point to) are marked incomplete.

Chris Lattner 21a79edb27 fix crashes when we only have a prototype for main.

Chris Lattner dadf4b369e Fix a crash that happens when mapping something like this: 
{ short, short }

to
  short

where the second short maps onto the second field of the first struct.  In
this case, the struct index is not aligned, so we should avoid calling
getLink(2), which asserts out.

Andrew Lenharth aa254d5f79 sure, I can set a flag, but if I never check it, why bother setting it? Should fix 20 programs :)

Chris Lattner d31a3d0e82 Finally fix (the right way) the problem where functions like this: 
void foo() {
  G = 1;
}

would have an empty DSGraph even though G (a global) is directly used
in the function.

Chris Lattner 531f9e92d4 This mega patch converts us from using Function::a{iterator|begin|end} to 
using Function::arg_{iterator|begin|end}.  Likewise Module::g* -> Module::global_*.

This patch is contributed by Gabor Greif, thanks!

Chris Lattner 76aa8e071b Allow the live interval analysis pass to be a bit more aggressive about 
numbering values in live ranges for physical registers.

The alpha backend currently generates code that looks like this:

  vreg = preg
...
  preg = vreg
  use preg
...
  preg = vreg
  use preg

etc.  Because vreg contains the value of preg coming in, each of the
copies back into preg contain that initial value as well.

In the case of the Alpha, this allows this testcase:

void "foo"(int %blah) {
        store int 5, int *%MyVar
        store int 12, int* %MyVar2
        ret void
}

to compile to:

foo:
        ldgp $29, 0($27)
        ldiq $0,5
        stl $0,MyVar
        ldiq $0,12
        stl $0,MyVar2
        ret $31,($26),1

instead of:

foo:
        ldgp $29, 0($27)
        bis $29,$29,$0
        ldiq $1,5
        bis $0,$0,$29
        stl $1,MyVar
        ldiq $1,12
        bis $0,$0,$29
        stl $1,MyVar2
        ret $31,($26),1

This does not seem to have any noticable effect on X86 code.

This fixes PR535.

Chris Lattner 7f26946709 constant fold FP_ROUND_INREG, ZERO_EXTEND_INREG, and SIGN_EXTEND_INREG 
This allows the alpha backend to compile:

bool %test(uint %P) {
        %c = seteq uint %P, 0
        ret bool %c
}

into:

test:
        ldgp $29, 0($27)
        ZAP $16,240,$0
        CMPEQ $0,0,$0
        AND $0,1,$0
        ret $31,($26),1

instead of:

test:
        ldgp $29, 0($27)
        ZAP $16,240,$0
        ldiq $1,0
        ZAP $1,240,$1
        CMPEQ $0,$1,$0
        AND $0,1,$0
        ret $31,($26),1

... and fixes PR534.
