62922d5727 Add a new flag for targets where setjmp/longjmp saves/restores the signal mask, 
and _setjmp/_longjmp should be used instead (for llvm.setjmp/llvm.longjmp).

96f29dbdbe Make this slightly more efficient by pushing actual type information down 
into the evaluator.  This shrinks a release build of instcombine's text
section from 216363 to 215975 bytes (on PPC).

92616caa1a Split SimpleConstantVal up into its components, so each Constant subclass gets 
a different enum value.  This allows 'classof' for these to be really simple,
not needing to call getType() anymore.

This speeds up isa/dyncast/etc for constants, and also makes them smaller.
For example, the text section of a release build of InstCombine.cpp shrinks
from 230037 bytes to 216363 bytes, a 6% reduction.

f32ef9a37f 1. Use SubtargetFeatures in llc/lli. 
2. Propagate feature "string" to all targets.

3. Implement use of SubtargetFeatures in PowerPCTargetSubtarget.

09a731071f 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.

be2fa8f86f 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.

b06ce2e026 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.  :(

a31708e6b3 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.
