710e995889 realize that instructions who match intrinsics that read memory read memory. 
Also, instructions with any nodes that are SDNPMayLoad also read memory.

dcc8b4f5d3 add a mayLoad property for machine instructions, a correlary to mayStore. 
This is currently not set by anything.

749c6f6b5e rename TargetInstrDescriptor -> TargetInstrDesc. 
Make MachineInstr::getDesc return a reference instead
of a pointer, since it can never be null.

0ff23966fe 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.

c8478d8b12 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.

2d51a4ce8f 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.

200c57e8ea 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!

a3355ffb3d 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).

8330b0e5d4 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.
