Patch #1 of Saem Ghani's Pass Manager refactoring.  From the man:

"All this should do is create what will eventually be the specialised
passmanagers.  Currently, the templates are inheriting them, once the
template specialisations' methods have been absorbed, patches
submitted method by method.  I'll nuke the specialisations and have
the new objects inherit directly from passmanagert, and sanitise the
world of all references to templates.

Added field noResults to Instruction.
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.

HP aCC chokes on this, but it's not required anyway: according to
the bzip2 homepage, only ancient (gcc 2.7.x ?) versions of GCC
require this? It certainly isn't needed for the current bzip2
sources.

MERRY CHRISTMAS EVERYONE!!! (what better way to spend christmas than
to try building LLVM on HP-UX! (the Right Way seems to be to tear out
the ancient STL that HP ship and use http://incubator.apache.org/stdcxx/ )

Unify the patterns for loads and stores.  Now offset addressing should be
supported.  This almost completes memory operations.
