359b65f782 Add a floating point killer pass. This pass runs before register 
allocaton on the X86 to add information to the machine code denoting
that our floating point stackifier cannot handle virtual point
register that are alive across basic blocks. This pass adds an
implicit def of all virtual floating point register at the end of each
basic block.

52b62de100 Modified cast so that it converts the int to a long before casting to 
a pointer.  This evades a warning emitted by GCC when we cast from
unsigned int (32 bit) to void * (64 bit) on SparcV9.

3c09636588 In getObjectType(), doxygenify comment, and take a pointer to the 
beginning of the archive member data as an argument.

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
size.

63438cc9b0 Add support for --debug-only=interpreter, to print out instrs before 
interpreting them.

Move support for getting the value of a ConstantExpr into
getConstantExprValue(), and add support for the rest of the different
kinds of ConstantExprs.  (I don't think I like ConstantExprs!)
This requires separate procedures executeShlInst() and executeShrInst().

Reduce the number of references to TheEE.

Get rid of an old comment mentioning annotations.

Fix exitCalled(), which was crashing the Interpreter. This was a
leftover from the return-value code refactoring.

01b2d61311 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,
and an implicit return value of int says it returns 32 bits.
Admittedly, this is a bit of a hack.

7152da38ef 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.

this point, the second operand must be a physical register (it cannot
be a virtual one).

8d1dbd2134 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.

9b527704f7 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.  :(

91de352796 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.

* Move a ReturnInst method out-of-line, so that the vtable and type info don't
  need to be emitted to every translation unit that uses the class.

542d991451 *** 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

* 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

c59c118e44 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.

This fixes PR77

ee8adb1955 This version of Linker.cpp works a lot better, but it's a little messy. Sorry. 
Use FileOpenable() instead of FileExists().
Create IsBytecode() predicate -- like IsArchive(), but for bytecode files.
Use IsBytecode() before trying to load any file as a bytecode file.

e9414cab00 Fix problems linking against the reoptimizer; _llvm_regAllocState must have 
externally-visible linkage, and SaveStateToModule must default to true for llc.
I don't remember why I made it const; perhaps it should be deconstified.

213904133d Operand numbers are now ints. Save the register allocation of the value 
each instruction produces as "operand" -1, and the other operands as 0
.. n, as before. PhyRegAlloc::saveState() is refactored into
PhyRegAlloc::saveStateForValue().

d77922f1a2 Do NOT inline self recursive calls into other functions. This is causing the 
pool allocator no end of trouble, and doesn't make a lot of sense anyway.  This
does not solve the problem with mutually recursive functions, but they are much less common.
