Chris Lattner 5916d7b6b1 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.

Evan Cheng 14c53b45f5 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.

Duraid Madina b43eb8c75b 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.

Evan Cheng 9ae486047e * Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead. 
* Added a pseudo instruction (for each target) that represent "return void".
  This is a workaround for lack of optional flag operand (return void is not
  lowered so it does not have a flag operand.)
