fe533cc4e6 Reorganized the Sparc backend to be more modular -- each different 
implementation of a Target{RegInfo, InstrInfo, Machine, etc} now has a separate
header and a separate implementation file.

This means that instead of a massive SparcInternals.h that forces a
recompilation of the whole target whenever a minor detail is changed, you should
only recompile a few files.

Note that SparcInternals.h is still around; its contents should be minimized.

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.

Get rid of ParseLongFilenameSection(), which is dead.

In ReadArchiveBuffer(), implement support for 4.4BSD/MacOSX long filenames.
This is kind of invasive, because they prepend the long filename to the archive
member data, and then lie about the size. So we have to keep track of the real

c299416f67 Fixed the CBE on Solaris/Sparc. We need to define the return value of 
the write() system call because it returns 64 bits on Solaris 64 bit,

be2b3fb417 Cleanup and restructure the code to make it easier to read and maintain. 
The only functionality change is that we now implement:
  Regression/Transforms/TailCallElim/intervening-inst.ll

Which is really kinda pointless, because it means that trivially dead code
does not interfere with -tce, but trivially dead code probably wouldn't be
around anytime when this pass is run anyway.

The point of including this change it to support other more aggressive
transformations when we have the analysis capabilities to do so.

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.

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.  :(

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.

  This dramatically reduces bytecode loading time of kc++, reducing time-to-jit
  kc++ --version to 17s from 33s

* Strength reduce several data structures which were left over from the

* Minor efficiency improvements
* Major efficiency improvement: In BytecodeParser::insertValue, do not allocate
  a new ValueTab entry just because some value exists with a large type.  This
  dramatically reduces the number of allocations/deallocations performed by the
  bytecode reader, and speeds up parsing of Kimwitu++ from 34s to 17s.  This is
  to help address PR127
