Misha Brukman 95e6287734 Booleans are types too. And they get stored in bytes. And InstructionSelection 
doesn't assert fail. And everyone's happy. Yay!

Misha Brukman 53d2de923a Add definitions for function headers from MRegisterInfo.h: 
Some functions are in X86RegisterInfo.cpp, others, because of the data they
need, are in X86RegisterClasses.cpp, which also defines some register classes:
byte, short, and int.

Misha Brukman 6e5d493e0f Check not only for MO_VirtualRegister, but MO_MachineRegister as well when

Chris Lattner 98cf1f5d64 - Eliminated the deferred symbol table stuff in Module & Function, it really 
wasn't an optimization and it was causing lots of bugs.

Chris Lattner b251c3d727 Eliminate the concept of a deferred symbol table. The optimization really isn't, 
and it causes obscure bugs to show up in passes.

Misha Brukman eaaceb1210 Add mapping in MachineFunction from SSA regs to Register Classes. Also, 
uncovered a bug where registers were not being put in a map if they were not
found...

Misha Brukman 310afc5f8c Thanks to the R8, R16, and R32 macros, I can now deal with registers that 
belong to different register classes easier.

Chris Lattner dcb4ac9594 Fix two bugs: 
* The globals vector was getting broken and unsorted, this caused vortex
   to get badly pessimized
 * Node offset handling was being handled really poorly, and in particular
   we were not merging types with offsets right.  This causes several graphs
   to be non-merged.

This will be used by the IPModRef class to do stuff, eventually perhaps the

Speaking of the TD pass, this also eliminates the self recursive case, which
was broken, and couldn't occur anyway.

Chris Lattner a7b0d4eb08 Stop representing scalars as explicit nodes in the graph. Now the only 
nodes in the graph are memory objects, which is very nice.  This also greatly
reduces the size and memory footprint for DSGraphs.  For example, the local
DSGraph for llu went from 65 to 13 nodes with this change.  As a side bonus,
dot seems to lay out the graphs slightly better too.  :)

Chris Lattner 7d5f19886d This fixes all kinds of problems with array handling. There are still bugs to

    * Make DSNode::TypeRec a full fledged DSTypeRec type.
    * Add methods used to update and access the typerecords elements
    * Add methods to query if and to cause a node to be completely folded
    * DSGraph construction doesn't use the allocation type for anything at all,
      now nodes get their type information based on how they are used.
    * Fixed a bug with global value handling introduced in the last checkin
    * GEP support is now much better, arrays are handled correctly.  The array
      flag is now updated in type records.  There are still cases that are not
      handled yet (we do not detect pessimizations), but getting much closer.

Also, move CallArgsDescriptor into this class instead of making it an
annotation on the machine instruction.
