Chris Lattner 8db52980b7 Minor changes, remove some debugging code that got checked in somehow.
Make sure to scope the NodeMap passed into cloneInto so that it doesn't point
to nodes that are deleted.  Add some FIXME's for future performance enhancements.

Chris Lattner f48eb7519a Only clone nodes that are needed in the caller, don't clone ALL aux calls. This improves
povray from having ~600K nodes and 300K call nodes to 65K nodes and 25K call nodes.

Chris Lattner d9da2678fc Fix a DSA bug that caused DSA to generate incredibly huge graphs and take forever to
do it on povray.  The problem is that we were not copying globals from callees to
callers unless the existed in both graphs.  We should have copied them in the case
where the global pointed to a node that was copied as well.

Chris Lattner 93e9878c2c SPECIFY a target data to initialize the CBE target with. Until now we have
been using the default target data layout object to lower malloc instructions,
causing us to allocate more memory than we needed!  This could improve the
performance of the CBE generated code substantially!

Brian Gaeke 427cec1395 TargetCacheInfo has been removed; its only uses were to propagate a constant
(16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's
dcache has 32-byte lines, so I'm not sure where the 16 came from. However, in
the interest of not breaking things any more than they already are, I'm going
to leave the constant alone.

Chris Lattner 1f4642c47c Handle passing constant integers to functions much more efficiently. Instead
of generating this code:

        mov %EAX, 4
        mov DWORD PTR [%ESP], %EAX
        mov %AX, 123
        movsx %EAX, %AX
        mov DWORD PTR [%ESP + 4], %EAX
        call Y

we now generate:
        mov DWORD PTR [%ESP], 4
        mov DWORD PTR [%ESP + 4], 123
        call Y

Which hurts the eyes less.  :)

Considering that register pressure around call sites is already high (with all
of the callee clobber registers n stuff), this may help a lot.

Chris Lattner 5c7d3cda78 Fix a minor code-quality issue. When passing 8 and 16-bit integer constants
to function calls, we would emit dead code, like this:

int Y(int, short, double);
int X() {
  Y(4, 123, 4);
}

--- Old
X:
        sub %ESP, 20
        mov %EAX, 4
        mov DWORD PTR [%ESP], %EAX
***     mov %AX, 123
        mov %AX, 123
        movsx %EAX, %AX
        mov DWORD PTR [%ESP + 4], %EAX
        fld QWORD PTR [.CPIX_0]
        fstp QWORD PTR [%ESP + 8]
        call Y
        mov %EAX, 0
        # IMPLICIT_USE %EAX %ESP
        add %ESP, 20
        ret

Now we emit:
X:
        sub %ESP, 20
        mov %EAX, 4
        mov DWORD PTR [%ESP], %EAX
        mov %AX, 123
        movsx %EAX, %AX
        mov DWORD PTR [%ESP + 4], %EAX
        fld QWORD PTR [.CPIX_0]
        fstp QWORD PTR [%ESP + 8]
        call Y
        mov %EAX, 0
        # IMPLICIT_USE %EAX %ESP
        add %ESP, 20
        ret

Next up, eliminate the mov AX and movsx entirely!

Chris Lattner 482cf01a1e Fix the "partial pool allocator" on em3d and others. The problem is that
DSNodes, unlike other GraphTraits nodes, can have null outgoing edges, and
df_iterator doesn't take this into consideration.  As a workaround, the
successor iterator now handles null nodes and 'indicates' that null has
no successors.
