44689264b2 Fairly major change: emit fixed sized allocas in the entry block as a variable, 
instead of a variable pointer and an alloca.  All accesses to the variable then
use the address-of operator to access it.  This plays better with the internal
GCC code generation phases, which bail early on functions which contain allocas.
It also makes the code a bit easier to read.

493103ea3b Actually, change it to use explicit new/delete, which is more likely to be 
optimized INTO an alloca

4681b27a92 Isolate machine-dependent use of <alloca.h> in "Support/Alloca.h", 
so that we can easily change its use to be conditional on the result of
an autoconf test later.

64ec8f36aa Fix bug: ADCE/2003-06-11-InvalidCFG.ll 
This was because we were deleting large chunks of functions without an exit block, because the post-dominance
information was not useful.  This broke crafty and twolf.

ba5c703619 Do not hastily change the Opcode from 'r' to 'i' type if we're not actually 
SETTING the operand to be an immediate or have verified that one of the operands
is really a SignExtended or Unextended immediate value already, which warrants
an 'i' opcode.

d61d0211ba * Changed Bcc instructions to behave like BPcc instructions 
* BPA and BPN do not take a %cc register as a parameter
* SLL/SRL/SRA{r,i}5 are there for a reason - they are ONLY 32-bit instructions
* Likewise, SLL/SRL/SRAX{r,i}6 are only 64-bit
* Added WRCCR{r,i} opcodes

1a3c1a6208 ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: 
The JIT is designed to code-generate a function at-a-time. That means that any
pass can only make local changes to its function. Period.

Because the Sparc PreSelection pass claims to be a BasicBlock pass while adding
globals to the Module, it cannot be run with the other passes, because by this
time, the globals have been output already by the JIT, and the addresses of any
globals appearing AFTER this point are not recognized.

However, the PreSelection pass is a requirement for correctness in the Sparc
codegen path, so it MUST be run.
