f83aae613c rename TargetInstrDescriptor -> TargetInstrDesc. 
Make MachineInstr::getDesc return a reference instead
of a pointer, since it can never be null.

57e851edfe Rename all the M_* flags to be namespace qualified enums, and switch 
all clients over to using predicates instead of these flags directly.
These are now private values which are only to be used to statically
initialize the tables.

b0e50db817 Move M_* flags down in the file. Move SchedClass up in the 
TargetInstrDescriptor class and shrink to 16-bits, saving a 
word in TargetInstrDescriptor.  Add some comments.

8b4b75c771 Change the 'isStore' inferrer to look for 'SDNPMayStore' 
instead of "ISD::STORE".  This allows us to mark target-specific dag
nodes as storing (such as ppc byteswap stores).  This allows us to remove
more explicit isStore flags from the .td files.

Finally, add a warning for when a .td file contains an explicit 
isStore and tblgen is able to infer it.

ed75a9c636 remove some old hacky code that tried to infer whether a store 
occured in a pattern, but failed miserably.  The new code works for
any instruction that has a store in its pattern, including all the 
x86 mem op mem instructions.

The only target-independent code that uses this is branch folding,
so this won't change anything in practice.

e61657979a now that computing CodegenDAGPatterns doesn't implicitly print stuff 
out, DAGISelEmitter can compute it in its ctor, which simplifies some code.

Now we can use CodegenDAGPatterns in other parts of tblgen that want access
to dag pattern info, woo!

1e2e4972ff Rather than having special rules like "intrinsics cannot 
throw exceptions", just mark intrinsics with the nounwind
attribute.  Likewise, mark intrinsics as readnone/readonly
and get rid of special aliasing logic (which didn't use
anything more than this anyway).

8e1a74fd21 Updated GenLibDeps.pl to employ "use strict" to help prevent uses of variables 
that have not yet been defined.

Removed used of grep and sed when parsing the results of "nm". This was
originally motivated because if the user has specified options to grep using
the environment variable GREP_OPTIONS this could break the script. Piping
through grep/sed/sort/uniq is also (to my understanding) not necessary, and
the equivalent operations can be done much faster in the Perl script.

Using a crude benchmark, these changes resulted in a 3x speedup in the
execution of GenLibDeps.pl.

c447b7a449 Rewrite the tblgen parser in a recursive descent style, eliminating the bison parser. 
This makes the parser much easier to understand, eliminates a ton of global variables,
and gives tblgen nice caret diagnostics.  It is also faster, but tblgen probably doesn't
care about performance.

There are a couple of FIXMEs which I will take care of next.
