055804accd Suggestions made by Chris: 
* Instead of a #define, use inline function
* Fix the name on the #define, errr... now inline function to be more logical:
  it doesn't CHECK the alignment, it PERFORMS the alignment
* To get string name of a Type*, use getDescription(), not getName()

- no more passing around a string pointer to set errors
  - no more returning booleans and checking for errors, we use C++ exceptions
* Broke functionality into 2 new classes, one reads from file, one from a stream

6dc46fce5a Convert PhyRegAlloc into a proper pass. 
PhyRegAlloc.cpp:
 Don't include TargetMachine.h or TargetRegInfo.h, because these are provided
  by PhyRegAlloc.h.
 Merge class RegisterAllocator into class PhyRegAlloc.
 Simplify & move ctor, dtor to PhyRegAlloc.h.
 Make some of PhyRegAlloc's reference members into pointer members,
  so they can be more easily messed with.
 MarkAllocatedRegs() becomes a member method, with fewer args.

PhyRegAlloc.h:
 Include Pass.h, TargetMachine.h and TargetRegInfo.h. Don't declare
  TargetRegInfo forward.
 Give AddedInstrns the obvious clear() method.
 Make some of PhyRegAlloc's reference members into pointer members,
  so they can be more easily messed with.
 Add prototype for markAllocatedRegs().

8502d4f3f8 This is effectively a complete rewrite of the globaldce algorithm, resulting 
in it being both shorter and more effective.  It no longer depends on the
callgraph, so one FIXME has been fixed.

Additionally, this pass was not able to delete recursive (but dead) functions
if they were pointed to by global variables which were also dead.  In fact
this pass had a lot of problems deleting functions which were only pointed
to by dead globals and other stuff.

Fixing this means that the entire EH library should be stripped away now from
programs that don't use sjlj or exceptions.

29a0f79c05 Don't explicitly use $SourceDir to find the tblgen files. This causes make 
some confusion when trying to generate files (it probably couldn't tell that
./file and $(SourceDir)/file may be the same file).
Now, just let VPATH find everything, and list the primary tblgen file first in
the list of dependencies so that we can just use $< to reference it in the make
rule.

This should hopefully fix the nightly tester.

e783801878 Updated to find source files using VPATH. This makes writing build rules 
much cleaner and easier.
Labeled .td as a suffix for tblgen files in Makefile.rules.
Modified build rules so that source files generated during the build are placed
in the build directory and not the source directory (and not in a Debug
directory).  This makes the system cleaner and allows us to have a read-only
source tree.

6b94d6a603 Reverting back to the previous revision. 
We want to check for length 5 because we might get the "llvm." string as the
name.  That string is in the LLVM namespace and should be checked as such.
We also don't have to worry about garbage data because (I believe) the string
class will return a valid value.  So, the switch statement will work and we
don't have to worry about the code wandering into segfault land.

dda7669997 Change the code to no longer compute the "type description" immediately when 
the type is analyzed.  Instead, only compute it when requested (with
getDescription), and cached for reuse later.

This dramatically speeds up LLVM in general because these descriptions almost
_never_ need to be constructed.  The only time they are used is when a type is
<<'d.  Printing of modules by themselves uses other code to print symbolic
types when possible, so these descriptions are really only used for debugging.

Also, this fixes the particularly bad case when lots of types get resolved to
each other, such as during linking of large programs.  In these cases, the type
descriptions would be repeatedly recomputed and discarded even though: A. noone
reads the description before it gets resolved, and B. many many resolutions
happen at intermediate steps, causing a HUGE waste of time.

Overall, this makes the getTypeDesc function much more light-weight, and fixes
bug: Assembler/2002-07-08-HugePerformanceProblem.llx, which went from taking
1048.770u/19.150s (which is 17.5 MINUTES, on apoc), to taking 0.020u/0.000s,
which is a nice little speedup.  :)
