956afdd1f2 Relax the "don't unroll loops containing calls" rule. Instead, when a loop contains a call, lower the 
unrolling threshold to the optimize-for-size threshold.  Basically, for loops containing calls, unrolling
can still be profitable as long as the loop is REALLY small.

464762ad1a Add intrinsic forms of mmx<->sse conversions. Notes: 
Omission of memory form of PI2PD is intentional; this
does not use an MMX register and does not put the chip
into MMX mode (PI2PS, oddly enough, does).
Operands of PI2PS follow the gcc builtin, not Intel.

a83eb43cb8 A script that tests a certain release candidate in several modes. It does a 
2-phase build of llvm and llvm-gcc, similar to what the buildbots do, and runs
the regression testsuite.

Things to do:

- Work out some bugs with llvm-gcc flags.
- Not all platforms support ObjC.
- Run the test-suite.

c7dd9d3840 Clarify the ownership model of LLVMContext and Module. Namely, contexts own 
modules are instantiated in them.  If the context is deleted, all of its owned
modules are also deleted.

892c337123 x86 vector shuffle lowering now relies only on target specific 
nodes to emit shuffles and don't do isel mask matching anymore.
- Add the selection of the remaining shuffle opcode (movddup)
- Introduce two new functions to "recognize" where we may get
potential folds and add several comments to them explaining why
they are not yet in the desidered shape.
- Add more patterns to fallback the case where we select
a specific shuffle opcode as if it could fold a load, but it
can't, so remap to a valid instruction.
- Add a couple of FIXMEs to address in the following days once
there's a good solution to the current folding problem.

273fed4827 Be more careful about when to do dynamic stack realignment. Since we have an 
option to disable base pointer usage, pay attention to it when deciding
if we can realign (if no base pointer and VLAs, we can't).

001e8a9350 Execute all Pass Printers even if -quiet is set. 
Follow the same logic in the LoopPass, ModulePass and CallGraphSCCPass printers,
as it was already used in the BasicBlockPass and FunctionPass printers. This is
more consistent.

The other option would have been to completely disable dumping the analysis
information. However, as this information is the only information printed if the
-analysis flag is set, calling opt would not do anything at all.
