4401d0a7a3 Change weight into a float so that we can take into account the 
nesting level when computing it. Right now the allocator uses:

    w = sum_over_defs_uses( 10 ^ nesting level );

4f98b79ef0 Add support for inactive intervals. This effectively reuses registers 
for live ranges that fall into assigned registers' holes.

9181e0ab5b Remove TwoAddressInstruction from the public headers and add an ID 
instead, since this pass doesn't expose any state to its users.

90aeecae42 Add TwoAddressInstructionPass to handle instructions that have two or 
more operands and the two first operands are constrained to be the
same. The pass takes an instruction of the form:

        a = b op c

and transforms it into:

        a = b
        a = a op c

and also preserves live variables.

8e2fcc7d79 Handle multiple virtual register definitions gracefully. 
Move some of the longer LiveIntervals::Interval method out of the
header and add debug information to them. Fix bug and simplify range
merging code.

457dd0b6c7 Add a new AliassetTracker::remove method. Because we need to be able to remove 
a pointer from an AliasSet, maintain the pointer values on a doubly linked
list instead of a singly linked list, to permit efficient removal from the
middle of the list.

29127b8825 Change interface of MachineOperand as follows: 
a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse()
    b) add isUse(), isDef()
    c) rename opHiBits32() to isHiBits32(),
              opLoBits32() to isLoBits32(),
              opHiBits64() to isHiBits64(),
              opLoBits64() to isLoBits64().

This results to much more readable code, for example compare
"op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used
very often in the code.

d4abe8d28a The recalclulate method was a nasty hack that was once used by the -cee pass, 
which never worked itself.  The cee pass still doesn't work, but it doesn't use
this method anymore anyway, so eliminate the method.

f158b46c54 This is a hack to make this file compile under g++-3.0.x; 
otherwise it can't decide what std::pair is. It seemed relatively
harmless.
