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.

Also, some minor cleanup.

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 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")>.

Jakob Stoklund Olesen 60e70e8fcf Add an (interleave A, B, ...) SetTheory operator.
This will interleave the elements from two or more lists.

David Greene af973b4f36 [AVX] Make Inits Foldable
Manage Inits in a FoldingSet.  This provides several benefits:

- Memory for Inits is properly managed

- Duplicate Inits are folded into Flyweights, saving memory

- It enforces const-correctness, protecting against certain classes
  of bugs

The above benefits allow Inits to be used in more contexts, which in
turn provides more dynamism to TableGen.  This enhanced capability
will be used by the AVX code generator to a fold common patterns
together.

Jim Grosbach 797cff0504 Consolidate some TableGen diagnostic helper functions.
TableGen had diagnostic printers sprinkled about in a few places. Pull them
together into a single location in Error.cpp.

Jakob Stoklund Olesen 72f4b85119 Prempt some obnoxious compiler from complaing about signed/unsigned
compares.

2^30 is actually the limit on the number of physical registers per
TargetRegisterInfo.h.

Jakob Stoklund Olesen fc205a5694 Teach TableGen to evaluate DAG expressions as set operations.
A TableGen backend can define how certain classes can be expanded into
ordered sets of defs, typically by evaluating a specific field in the
record. The SetTheory class can then evaluate DAG expressions that refer
to these named sets.

A number of standard set and list operations are predefined, and the
backend can add more specialized operators if needed. The -print-sets
backend is used by SetTheory.td to provide examples.

This is intended to simplify how register classes are defined:

  def GR32_NOSP : RegisterClass<"X86", [i32], 32, (sub GR32, ESP)>;
