Chandler Carruth 91d19d8e93 Sort the #include lines for utils/... 
I've tried to find main moudle headers where possible, but the TableGen
stuff may warrant someone else looking at it.

Rafael Espindola 7296139d5e Fix a build problem with xlc. The error message was 
"../llvm-git/utils/TableGen/CodeGenSchedule.cpp", line 1594.12: 1540-0218 (S) The call does not match any parameter list for "operator+".
"../llvm-git/include/llvm/ADT/STLExtras.h", line 130.1: 1540-1283 (I) "template <class _Iterator, class Func> llvm::operator+(mapped_iterator<_Iterator,Func>::difference_type, const mapped_iterator<_Iterator,Func> &)" is not a viable candidate.

Patch by Kai.

Joerg Sonnenberger 635debe85b Remove exception handling usage from tblgen. 
Most places can use PrintFatalError as the unwinding mechanism was not
used for anything other than printing the error. The single exception
was CodeGenDAGPatterns.cpp, where intermediate errors during type
resolution were ignored to simplify incremental platform development.
This use is replaced by an error flag in TreePattern and bailout earlier
in various places if it is set.

Joerg Sonnenberger 7090937330 Don't use stack unwinding to provide the location information for 
SetTheory, but pass down the location explicitly.

Sean Silva fb509ed156 tblgen: Mechanically move dynamic_cast<> to dyn_cast<>. 
Some of these dyn_cast<>'s would be better phrased as isa<> or cast<>.
That will happen in a future patch.

There are also two dyn_cast_or_null<>'s slipped in instead of
dyn_cast<>'s, since they were causing crashes with just dyn_cast<>.

Andrew Trick d0b9c44583 TableGen subtarget emitter cleanup. 
Consistently evaluate Aliases and Sequences recursively.

Andrew Trick 9e1deb69b9 Added instregex support to TableGen subtarget emitter. 
This allows the processor-specific machine model to override selected
base opcodes without any fanciness.
e.g. InstRW<[CoreXWriteVANDP], (instregex "VANDP")>.

Andrew Trick da984b1aa9 TableGen subtarget emitter, nearly first class support for SchedAlias. 
A processor can now arbitrarily alias one SchedWrite onto
another. Only the SchedAlias definition need be within the processor
model. The aliased SchedWrite may be a SchedVariant, WriteSequence, or
transitively refer to another alias.

Andrew Trick 9257b8f8bb Machine Model (-schedmodel only). Added SchedAliases. 
Allow subtargets to tie SchedReadWrite types to processor specific
sequences or variants.

Andrew Trick 87255e340e I'm introducing a new machine model to simultaneously allow simple 
subtarget CPU descriptions and support new features of
MachineScheduler.

MachineModel has three categories of data:
1) Basic properties for coarse grained instruction cost model.
2) Scheduler Read/Write resources for simple per-opcode and operand cost model (TBD).
3) Instruction itineraties for detailed per-cycle reservation tables.

These will all live side-by-side. Any subtarget can use any
combination of them. Instruction itineraries will not change in the
near term. In the long run, I expect them to only be relevant for
in-order VLIW machines that have complex contraints and require a
precise scheduling/bundling model. Once itineraries are only actively
used by VLIW-ish targets, they could be replaced by something more
appropriate for those targets.

This tablegen backend rewrite sets things up for introducing
MachineModel type #2: per opcode/operand cost model.
