typedIdent no longer destroys attachments

When transforming Idents to qualified Selects, typedIdent used to forget
about carrying original attachments to the resulting tree. Not anymore.

SI-6288 Perfecting positions

- Adds tests for unapplySeq and unapply: Boolean.
Both seem to be well positioned after the previous
changes.

The call to `Option#get` on the result of the
unapply method was unpositioned and ended up
with the position of the `match`.

ICode generation was assigning the position of
the last label jump to all jumps to that particular
label def.
This problem is particularly annoying under the new
pattern matcher: a breakpoint in the body of the final
case will be triggered on the way out of the body of
any other case.
Thanks to @dragos for the expert guidance as we
wended our way through GenICode to the troublesome
code. Chalk up another bug for mutability.
I believe that the ICode output should be stable
enough to use a a .check file, if it proves otherwise
we should make it so.

`atPos(pos) { ... }` doesn't descend into children of
already positioned trees, we need to manually set the
position of `CODE.REF(binder)` to that of the stunt double
`Ident(nme.SELECTOR_DUMMY)`.

lazy annotations for some of the cases.
Also removed forcing for PackageDef annotations as we currently
don't support them.

We were losing track of parameter names in two places:
1. Uncurry was using fresh names for the apply method
parameters during Function expansion. (The parameter names
in the tree were actually correct, they just had synthetic
symbols with "x$1" etc.)
2. When adding specialized overrides, the parameter names
of the overriden method were used, rather than the parameter
names from the overriding method in the class to which we are
adding methods.
The upshot of this is that when you're stopped in the debugger in
the body of, say, `(i: Int) => i * i`, you see `v1` rather than `i`.
This commit changes Uncurry and SpecializeTypes to remedy this.

Lex Spoon noticed what appeared to be duplicate symbols
in methods read from classfiles. The duplicates turned out
to be type skolems, which because they're not supposed to
be pickled in the first place (right?) are unpickled
without turning back into skolems. Now pickler is careful
to deskolemize before writing anything down.
The effort implied by test case is more than can possibly
be justified for this obscure compiler corner, but I'll
chalk it up to reflection exploration.

Fix for SI-6595, lost modifiers in early defs.

| | | | | | | | | | |
| | | | | | | | | | |
| | | | | | | | | | |
| | | | | | | | | | | |
Saw this by accident; the trees created for early defs would
wholesale replace the modifiers with PRESUPER rather than
combining them. FINAL was lost that way, as would be any other
modifiers which might be valid there.

When all the logic in a method is for symbol creation,
and then at the last minute it throws on a hastily zipped
ValDef, it's really not a tree generation method, it's a
symbol creation method.
Eliminated redundancy and overgeneralization; marked some
bits for further de-duplication. Did my best with my limited
archeological skills to document what is supposed to be
happening in eliminateModuleDefs.

Reification of renamed imports is done by catching Selects with name != their tree.symbol.name,
replacing this name with tree.symbol.name, and then doing reifyProduct in case

This used to crash, as both the package and the package object
had the synthetic method in `decls`, and the typer tried to add
the tree to both places.
Now, synthetics in the package object are excluded from the pacakge

SI-6558: typecheck lazy annotation info using non-silent context

Make context for typing lazy annotations always non-silent. If lazy annotation info was created in local (silent) context, error could go unnoticed because later they would still use silent typer for typing the annotation.

The assertion that the class being mixed from should be an implclass
seems reasonable, but the flag isn't always set. In order to stop the
bleeding this fix turns the assertion into a debug warning. Issue SI-6782
