286169ff60 Remove and simplify some of the bewildering collection of isFOORegister 
methods which have strangely different semantics in different backends,
and noone knew what any did.

Getting rid of these ALSO allows the dependence of MachineInstr.h on
MRegisterInfo.h to be removed, which makes me much happier, and probably
alkis too.  :)

2a8df1739b Fix failing test cases with joined live intervals. It turns out that 
when joining we need to check if we overlap with the second interval
or any of its aliases.

Also make joining intervals the default.

llvm-svn: 10973

b4745bda05 Add option to join live intervals. Two intervals are joined if there 
is a move between two registers, at least one of the registers is
virtual and the two live intervals do not overlap.

This results in about 40% reduction in intervals, 30% decrease in the
register allocators running time and a 20% increase in peephole
optimizations (mainly move eliminations).

The option can be enabled by passing -join-liveintervals where
appropriate.

fc01aac4d8 Add coalescing to register allocator. A hint is added to each interval 
which denotes the register we would like to be assigned to (virtual or
physical). In register allocation, if this hint exists and we can map
it to a physical register (it is either a physical register or it is a
virtual register that already got assigned to a physical one) we use
that register if it is available instead of a random one in the free
pool.

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.

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.

138a3fc9ab Completely eliminate the per-machine-instruction regsUsed set. 
This substantially shrinks the size of each machine instruction, which should
make allocation faster and the cache footprint of the machine code lighter.

b047a0d449 All callers of these methods actually wanted them to preserve the flags, 
so get rid of the def/use parameters that were getting passed in.

**** This now changes the semantics of these methods to preserve the flags,
     not clobber them!
