weren't filtering out non-object types. Do so, fixing PR7851.

conversions on the substituted non-type template arguments of a class
template partial specialization. C++ [temp.class.spec]p8 actually
prohibits all of the cases where this code would have fired.

Hey, it's better than having to deal with variadic templates here!

specializations. We weren't dealing with any of the cases where the
type of the non-type template argument differs from the type of the
corresponding template parameter in the primary template. We would
think that the template parameter in the partial specialization was
not deducible (and warn about it, incorrectly), then fail to convert a
deduced parameter to the type of the template parameter in the partial
specialization (which may involve truncation, among other
things). Fixes PR8905.

Don't bother value numbering instructions with void types in GVN. In theory this should allow us to insert
fewer things into the value numbering maps, but any speedup is beneath the noise threshold on my machine
on 403.gcc.

This code was a temporary workaround due to the lack of a dynamic loader plugin
for the Linux platform that has bit rotted over time.  Instead of replacing this
hack with another a proper plugin will be developed instead.

The analysis will be needed by both the greedy register allocator and the
X86FloatingPoint pass. It only needs to be computed once when the CFG doesn't
change.

This pass is very fast, usually showing up as 0.0% wall time.

Clarify terminology, settling on referring to what was the "number table" as the "leader table", and

case where a static caller is itself inlined everywhere else, and
thus may go away if it doesn't get too big due to inlining other
things into it.  If there are references to the caller other than
calls, it will not be removed; account for this.
This results in same-day completion of the case in PR8853.

Branch instructions don't produce values, so there's no need to generate a value number for them.  This
avoids adding them to the various value numbering tables, resulting in a minor (~3%) speedup for GVN
