1736f44b1d Improve encapsulation in the Loop and LoopInfo classes by eliminating the 
getSubLoops/getTopLevelLoops methods, replacing them with iterator-based
accessors.

cbe72d0381 Add a separate list of fixed intervals. This improves the running time 
of the register allocator as follows:

       before   after
mesa   2.3790  1.5994
vpr    2.6008  1.2078
gcc    1.9840  0.5273
mcf    0.2569  0.0470
eon    1.8468  1.4359
twolf  0.9475  0.2004
burg   1.6807  1.3300
lambda 1.2191  0.3764

Speedups range anyware from 30% to over 400% :-)

496be157cc Currently we cannot handle two-address instructions of the form: 
A = B op C where A == C, but this cannot really occur in practice
because of SSA form. Add an assert to check that just to be safe.

4a673d0bf9 Not all platforms supports sighandler_t, so I changed it to use the older 
return value from signal() (which should be the same type; it's just not
typedef'd).
This fixes the build on Solaris.

46fdc8ce43 Add new ExecutionEngine::getGlobalValueAtAddress method, which can efficiently 
turn a memory address back into the LLVM global object that starts at that
address.  Note that this won't cause any additional datastructures to be built
for clients of the EE that don't need this information.

Also modified some code to not access the GlobalAddress map directly.

412295aeaa Further revisions of the FDHandle idea. In this version we use ownership 
semantics that are the same as those used by std::auto_ptr.  This allows
copying of FDHandle's, but copying transfers ownership.

8157eb7140 Reserve ECX and EDI instead of EBX and EDI. Since EBX is a callee 
saved register it has a longer free range than ECX (which is defined
every time there is a fnuction call) which makes ECX a better register
to reserve.

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.
