bbbe5d71d2 The flag modifications weren't picking up the old values of the 
flags before. Save them in a temporary variable, then restore them from the
temporary after creating the new constant.

a87f53efca Move target specific code to target files. The new MachineCodeEmitter 
class is actually target independent!

495826a0e5 Fix induction variable name clash in for loops, in finishFunction(). 
Modify new MachineOperand so that its flags match the old MachineOperand's
 flags, for the flags that matter.

a9a5c77dd4 Since malloc is no longer used, no need to free() memory. 
Fixed BasicBlock patching by supplying correct type for the displacement.

e1a9c59304 mmap() seems to be failing on Sparc, so just use malloc()/free() .

4931c59635 Link in Sparc libs for the JIT, even on X86 to be able to support debugging 
of Sparc JIT (printing out instrs) on X86. Con: this increases linking time.

afffd58fe6 Allow for specification of which JIT to run on the commandline. 
`lli -march=x86' or `lli -march=sparc' will forcefully select the JIT even on a
different platform. Running lli without the -march option will select the JIT
for the platform that it's currently running on.

Pro: can test Sparc JIT (debug printing mode) on X86 -- faster to compile/link
LLVM source base to test changes.
Con: Linking lli on x86 now pulls in all the Sparc libs -> longer link time
(but X86 can bear it, right?)

In the future, perhaps this should be a ./configure option to enable/disable
target JITting...

46f2fc75da Make sure that globals are emitted AFTER the passmanager is set up for the JIT, 
because the globals may refer to functions that need to be compiled!
