b1e1180ca0 1. Use SubtargetFeatures in llc/lli. 
2. Propagate feature "string" to all targets.

3. Implement use of SubtargetFeatures in PowerPCTargetSubtarget.

b3302db18a This new class provides support for platform specific "features". The intent 
is to manage processor specific attributes from the command line.  See examples
of use in llc/lli and PowerPCTargetSubtarget.

1d4d414111 First pass at the DAG Combiner. It isn't used anywhere yet, but it should 
be mostly functional.  It currently has all folds from SelectionDAG.cpp
that do not involve a condition code.

d6a80778e5 Allow physregs to occur in the dag with multiple types. Though I don't like 
this, it is a requirement on PPC, which can have an f32 value in r3 at one
point in a function and a f64 value in r3 at another point.  :(

5839bf2b3b Change ConstantPoolSDNode to actually hold the Constant itself instead of 
putting it into the constant pool.  This allows the isel machinery to
create constants that it will end up deciding are not needed, without them
ending up in the resultant function constant pool.

0a262ba7c3 For PR616: 
These patches make threading optional in LLVM. The configuration scripts are now
modified to accept a --disable-threads switch. If this is used, the Mutex class
will be implemented with all functions as no-op. Furthermore, linking against
libpthread will not be done. Finally, the ParallelJIT example needs libpthread
so its makefile was changed to always add -lpthread to the link line.

c44fff472c Keep the killed/dead sets sorted, so that "KillsRegister" can do a quick 
binary search to test for membership.  This speeds up LLC a bit more on KC++,
e.g. on itanium from 16.6974s to 14.8272s, PPC from 11.4926s to 10.7089s and
X86 from 10.8128s to 9.7943s, with no difference in generated code (like all
of the RA patches).

With these changes, isel is the slowest pass for PPC/X86, but linscan+live
intervals is still > 50% of the compile time for itanium.  More work could
be done, but this is the last for now.

e0cbf970ac Change live variables from using multimaps to using maps of vectors and 
rearrange some of the accessors to be more efficient.

This makes it much more efficient to iterate over all of the things with the
same value.  This speeds up liveintervals analysis from 8.63s to 3.79s with
a release build of llc on kc++ with -march=ia64.  This also speeds up live
var from 1.66s -> 0.87s as well, reducing total llc time from 20.1s->15.2s.

This also speeds up other targets slightly, e.g. llc time on X86 from 16.84
-> 16.45s, and PPC from 17.64->17.03s.

d5d0f9bd20 Eliminate the RegSDNode class, which 3 nodes (CopyFromReg/CopyToReg/ImplicitDef) 
used to tack a register number onto the node.

Instead of doing this, make a new node, RegisterSDNode, which is a leaf
containing a register number.  These three operations just become normal
DAG nodes now, instead of requiring special handling.

Note that with this change, it is no longer correct to make illegal
CopyFromReg/CopyToReg nodes.  The legalizer will not touch them, and this
is bad, so don't do it. :)

e5d63829fd Some SELECT_CC cleanups: 
1. move assertions for node creation to getNode()
2. legalize the values returned in ExpandOp immediately
3. Move select_cc optimizations from SELECT's getNode() to SELECT_CC's,
   allowing them to be cleaned up significantly.

This paves the way to pick up additional optimizations on SELECT_CC, such
as sum-of-absolute-differences.

7cf7e3f33f Eliminate the SetCCSDNode in favor of a CondCodeSDNode class. This pulls the 
CC out of the SetCC operation, making SETCC a standard ternary operation and
CC's a standard DAG leaf.  This will make it possible for other node to use
CC's as operands in the future...

6a9746127a Like constants, globals on some platforms are GOT relative. This means they have to be allocated 
near the GOT, which new doesn't do.  So break out the allocate into a new function.

Also move GOT index handling into JITResolver.  This lets it update the mapping when a Lazy
function is JITed.  It doesn't managed the table, just the mapping.  Note that this is
still non-ideal, as any function that takes a function address should also take a GOT
index, but that is a lot of changes.  The relocation resolve process updates any GOT entry
it sees is out of date.
