e4977cf750 Make structs and arrays first-class types, and add assembly
and bitcode support for the extractvalue and insertvalue
instructions and constant expressions.

Note that this does not yet include CodeGen support.

844731a7f1 Clean up the use of static and anonymous namespaces. This turned up
several things that were neither in an anonymous namespace nor static
but not intended to be global.

58d74910c6 Reimplement the parameter attributes support, phase #1. hilights:
1. There is now a "PAListPtr" class, which is a smart pointer around
   the underlying uniqued parameter attribute list object, and manages
   its refcount.  It is now impossible to mess up the refcount.
2. PAListPtr is now the main interface to the underlying object, and
   the underlying object is now completely opaque.
3. Implementation details like SmallVector and FoldingSet are now no
   longer part of the interface.
4. You can create a PAListPtr with an arbitrary sequence of
   ParamAttrsWithIndex's, no need to make a SmallVector of a specific 
   size (you can just use an array or scalar or vector if you wish).
5. All the client code that had to check for a null pointer before
   dereferencing the pointer is simplified to just access the 
   PAListPtr directly.
6. The interfaces for adding attrs to a list and removing them is a
   bit simpler.

Phase #2 will rename some stuff (e.g. PAListPtr) and do other less 
invasive changes.

dc024674ff Fix PR1146: parameter attributes are longer part of
the function type, instead they belong to functions
and function calls.  This is an updated and slightly
corrected version of Reid Spencer's original patch.
The only known problem is that auto-upgrading of
bitcode files doesn't seem to work properly (see
test/Bitcode/AutoUpgradeIntrinsics.ll).  Hopefully
a bitcode guru (who might that be? :) ) will fix it.

33f1d5b328 Fix a nasty problem where we would miss enumeration of some types. This fixes
issues with CE_CAST etc.

7a303d1591 enumerate the operands of a constant before we enumerate the constant itself
This avoids fwd references in the reader.

6da91d3c2c optimize constant layout. This fixes encoding of 181.mcf (by ensuring
integer structure idx's are emitted before constant expr geps) and shrinks
files slightly.  For example kc++ shrinks from 4326188 to 4240128 bytes.

198f34ac35 move some code around, fix a bug in the reader reading globalinits (which
I just introduced), stub out function reading, purge aggregate values from
the value table before reading functions.

fd57cecd2c Initial support for writing bitcode files. This currently only writes types,
the type symtab, and global/function protos, and is missing the important
size optimization, but it is a place to start.
