6831a81599 Completely rewrite libcall insertion by the legalizer, providing the 
following handy-dandy properties:

1. it is always correct now
2. it is much faster than before
3. it is easier to understand

This implementation builds off of the recent simplifications of the
legalizer that made it single-pass instead of iterative.

This fixes JM/lencod, JM/ldecod, and
CodeGen/Generic/2006-02-12-InsertLibcall.ll (at least on PPC).

fae9f1cb34 Added SelectionDAG::InsertISelMapEntry(). This is used to workaround the gcc 
problem where it inline the map insertion call too aggressively. Before this
change it was producing a frame size of 24k for Select_store(), now it's down
to 10k (by calling this method rather than calling the map insertion operator).

6ae46c4c87 More changes to reduce frame size. 
Move all getTargetNode() out of SelectionDAG.h into SelectionDAG.cpp. This
prevents them from being inlined.
Change getTargetNode() so they return SDNode * instead of SDOperand to prevent
copying. It should also help compilation speed.

593c95878b Fix a nasty problem on two-address machines in the following situation: 
store EAX -> [ss#0]
[ss#0] += 1
...
use(EAX)

In this case, it is not valid to rewrite this as:


store EAX -> [ss#0]
EAX += 1
store EAX -> [ss#0]  ;;; this would also delete the store above
...
use(EAX)

... because EAX is not a dead at that point.  Keep track of which registers
we are allowed to clobber, and which ones we aren't, and don't clobber the
ones we're not supposed to.  :)

This should resolve the issues on X86 last night.
