a2ac517a20 Emit & read more compressed bytecode by not emitting a bytecodeblock for 
each basic block in function.  Instead, just emit a stream of instructions,
chopping up basic blocks based on when we find terminator instructions.  This
saves a fairly substantial chunk of bytecode space.  In stripped, sample
cases, for example, we get this reduction in size:

197.parser: 163036 -> 137180:  18.8% reduction
254.gap   : 844936 -> 689392:  22.6%
255.vortex: 621724 -> 528444:  17.7%

...

Not bad for something this simple.  :)  Note that this doesn't require a new
bytecode version number at all, though version 1.1 should not need to support
the old format.

e9269b7cc5 Add an option to enable the SSA based peephole optimizer. 
Eventually this pass will provide substantially better code in the interim between when we
have a crappy isel and nice isel.  Unfortunately doing so requires fixing the backend to
actually SUPPORT all of the fancy addressing modes that we now generate, and writing a DCE
pass for machine code.  Each of these is a fairly substantial job, so this will remain disabled
for the immediate future.  :(

6f1c35bc68 Add a new SSA-based peephole optimizer which includes copy propagation and 
folding of instructions into addressing modes.  This creates lots of dead
instructions, which are currently not deleted.  It also creates a lot of
instructions that the X86 backend currently cannot handle.  :(

acb0d474e9 Go back to allocating memory for each constant separately. Since SPARCs do not 
allow unaligned loads, that is probably the problem I've been seeing in numerous
SPARC test cases failing. X86, on the other hand, just slows down unaligned
accesses, since it must make 2 aligned accesses for each unaligned one.

54a3f2b134 *** Significantly speed up type resultion 
This change speeds up type resolution by checking to see if a type is
  recursive, and if it's not, using a more efficient algorithm.

  kc++ --version to 17s from 33s

7164a8a7ea ISO 9899 7.13.2.1 (3) says that "[...] the values of objects of automatic 
storage duration that are local to the function containing the invocation of the
[...] setjmp macro that do not have volatile-qualified type and have been
changed between the setjmp invocation and longjmp call are indeterminate."

As such, we have to mark all variables in a function that uses 'invoke' as
volatile.

* There is now only one pass to print out assembly instead of two
* It is a FunctionPass
* The Module-level printing of globals is now in doFinalization() method of the
  FunctionPass
* The code has been reformatted to follow LLVM coding standards
* Some comments, not all, were doxygenified
* Last but not least, the function to create an instance of this pass is also no
  longer a method in the UltraSparc class.

c6a7c83333 Change all machine basic block modifier functions in MRegisterInfo to 
return the number of instructions added to/removed from the basic block
passed as their first argument.

Note: This is only needed because we use a std::vector instead of an
ilist to keep MachineBasicBlock instructions. Inserting an instruction
to a MachineBasicBlock invalidates all iterators to the basic
block. The return value can be used to update an index to the machine
basic block instruction vector and circumvent the iterator elimination
problem but this is really not needed if we move to a better
representation.
