4dc25a234c Make x86-64 JIT changes Darwin-specific.

0f1ba9dee5 Add a NullFolder class that doesn't fold constants. 
This may be used as the second IRBuilder template
parameter, the idea being that people learning LLVM
may find it helpful (several people asked on IRC
if it was possible to turn off constant folding
because it made it hard for them to see what was
going on).  Compiles, but otherwise completely
untested.

37da9e9dbd Extend ScalarEvolution's executesAtLeastOnce logic to be able to 
continue past the first conditional branch when looking for a
relevant test. This helps it avoid using MAX expressions in
loop trip counts in more cases.

74bf5907fa In the absence of a linker to build the GOT, use the 32-bit 
non_lazy_ptr mechanism on x86-64 Darwin JIT.  Fixes a bunch
of last night's failures.

718fcee02d Some fixes for x86-64 JIT. Make it use small code 
model, except for external calls; this makes
addressing modes PC-relative.  Incomplete.

The assertion at the top of Emitter::runOnMachineFunction
was obviously bogus (always true) so I removed it.
If someone knows what the correct test should be to cover
all the various targets, please fix.

ae09ade343 Implement support for simplifying vector comparisons by 0.0 and 1.0 like we 
do for scalars.  Patch contributed by Nicolas Capens

This also generalizes the previous xforms to work on long double, now that 
isExactlyValue works for long double.

cac74d2a10 Make it possible to use different constant 
folding policies with IRBuilder.  The default,
provided by ConstantFolder, is to do minimal
folding like now: what ConstantExpr provides.
An alternative is to use TargetFolder, which
uses target information to fold constants more.

type lattice value for an Argument*, giving clients the opportunity to
use something other than Top for it if they choose to."
