a35ef6350d linkonce symbols have an extra indirection, just like weak ones do. This fixes
Prolangs-C++/family and Prolangs-C++/primes.

c9a5ef524a Fix a compile crash building MultiSource/Applications/d with the new front-end.
The PPC backend was generating random shift counts in this case, due to an
uninitialized variable.

2f690c84fa Implement a few symbolic constant folding things. X ? Y : Y is Y.
Fold:
seteq ({ short }* cast (int 1 to { short }*), { short }* null)
setlt ({ short }* cast (int 1 to { short }*), { short }* cast (int 2 to { short }*))

to false/true.  These last two commonly occur in the output of compilers that
tag integers, like cozmic's scheme compiler.

Tested by Regression/Assembler/ConstantExprFold.llx

7f7b730d79 Patch #6's in Saem's refactor-the-passmanager patch series. From him:
This sanitises the world, blows away the specialisations and adds
traits per passmanager type -- seemed most natural.

0b8e076d0b 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.

2b4ea795a2 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.

171049d10f * Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead.

  This is a workaround for lack of optional flag operand (return void is not
  lowered so it does not have a flag operand.)
