4bbd1c455f Added a Flags field to TargetOperandInfo. Currently the only flag is 
M_LOOK_UP_PTR_REG_CLASS which allows the register class of the operand to be
resolved via a callback at runtime.

16022f0a6a Improve error output. Use the third parameter of the "catch" command to 
capture the error output from the exec option. This generally will capture
the stderr messages generated by the tools. This information is then
printed if the test fails. This helps to recognize more quickly what the
error was. Otherwise, this information is lost.

8dbff8efda Make some changes suggested by Chris: 
1. Remove the LLVM_DO_NOT_BUILD feature (not needed any more)
2. Ensure that lib/VMCore gets built first. This needs to be done because
   VMCore now uses tblgen to generate the Intrinsics header which are
   needed in other libraries. In parallel builds, this can cause problems.

94297e068f Use DIRS here instead of PARALLEL_DIRS, as VMCore has to be built before the 
other dirs (for Intrinsics.gen).  :(

00f391f87b Fixed a LowerCallTo and LowerArguments bug. They were introducing illegal 
VBIT_VECTOR nodes. There were some confusion about the semantics of
getPackedTypeBreakdown(). e.g. for <4 x f32> it returns 1 and v4f32, not 4,
and f32.

4252704561 When we legalize target nodes, do not use getNode to create a new node, 
use UpdateNodeOperands to just update the operands!  This is important because
getNode will allocate a new node if the node returns a flag and this breaks
assumptions in the legalizer that you can legalize some things multiple times
and get exactly the same results.

This latent bug was exposed by my ppc patch last night, and this fixes
gsm/toast.

03c70b7f27 Switch PPC over to a call-selection model where the lowering code creates 
the copyto/fromregs instead of making the PPCISD::CALL selection code create
them.  This vastly simplifies the selection code, and moves the ABI handling
parts into one place.

348883611c 3 changes, 2 of which are cleanup one of which changes codegen: 
1. Rearrange code a bit so that the special case doesn't require indenting lots
   of code.
2. Add comments describing PPC calling convention.
3. Only round up to 56-bytes of stack space for an outgoing call if the callee
   is varargs.  This saves a bit of stack space.

b5271a0f4c Instead of implementing LowerCallTo directly, let the default impl produce an 
ISD::CALL node, then custom lower that.  This means that we only have to handle
LEGAL call operands/results, not every possible type.  This allows us to
simplify the call code, shrinking it by about 1/3.
