783084211a For PR521:
With these patches we implement the ability for the Linker library to
keep track of which libraries were actually bytecode files (not archives)
and cause their users to remove such files from the list of libraries to
pass to the native linker.

6c01df15ac Enhance the shift-shift folding code to allow a no-op cast to occur in between
the shifts.

This allows us to fold this (which is the 'integer add a constant' sequence
from cozmic's scheme compmiler):

int %x(uint %anf-temporary776) {
        %anf-temporary777 = shr uint %anf-temporary776, ubyte 1
        %anf-temporary800 = cast uint %anf-temporary777 to int
        %anf-temporary804 = shl int %anf-temporary800, ubyte 1
        %anf-temporary805 = add int %anf-temporary804, -2
        %anf-temporary806 = or int %anf-temporary805, 1
        ret int %anf-temporary806
}

into this:

int %x(uint %anf-temporary776) {
        %anf-temporary776 = cast uint %anf-temporary776 to int
        %anf-temporary776.mask1 = add int %anf-temporary776, -2
        %anf-temporary805 = or int %anf-temporary776.mask1, 1
        ret int %anf-temporary805
}

note that instcombine already knew how to eliminate the AND that the two
shifts fold into.  This is tested by InstCombine/shift.ll:test26

ee327e57d2 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.

"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.

231b11ba87 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.

e009e40008 this is a hack, which may or may not hang around. In short:
whimper out of doing things the Right Way, and hack up a generic
'BRCALL' instruction, that gets generated when calls are lowered.
This gets selected by hand in the DAG isel, where it gets turned
into real (i.e. in tablegen) br.call instructions.

BUG: this dies on void calls, but seems to work otherwise?
