Move code from Global/SymbolTable to separate Reporting traits to
start carving out an interface in scala.reflect.internal.Reporting,
with internals in scala.tools.nsc. Reporting is mixed into the cake.
It contains a nested class PerRunReporting.
Should do the same for debugging/logging.
The idea is that CompilationUnit and Global forward all reporting
to Reporter. The Reporting trait contains these forwarders, and
PerRunReporting, which accumulates warning state during a run.
In the process, I slightly changed the behavior of `globalError`
in reflect.internal.SymbolTable: it used to abort, weirdly.
I assume that was dummy behavior to avoid introducing an abstract method.
It's immediately overridden in Global, and I couldn't find any other subclasses,
so I don't think the behavior in SymbolTable was ever observed.
Provide necessary hooks for scala.reflect.macros.Parsers#parse.
See scala/reflect/macros/contexts/Parsers.scala's parse method,
which overrides the reporter to detect when parsing goes wrong.
This should be refactored, but that goes beyond the scope of this PR.
Don't pop empty macro context stack.
(Ran into this while reworking -Xfatal-warnings logic.)
Fix -Xfatal-warnings behavior (and check files): it wasn't meant to
influence warning reporting, except for emitting one final error;
if necessary to fail the compile (when warnings but no errors were reported).
Warnings should stay warnings.
This was refactored in fbbbb22946, but we soon seem to have relapsed.
An hour of gitfu did not lead to where it went wrong. Must've been a merge.

Refactor to reduce the Reporter interface. Working towards
minimal interfaces in scala.reflect.internal that can be consumed by sbt/IDE/....
The scala.tools.nsc package is entirely private to the compiler (in principle).
A `Reporter` should only be used to inform (info/warning/error). No state.
Ideally, we'd move to having only one reporter, whose lifetime is adjusted
appropriately (from per-run in general to per-context for type checking,
so errors can be buffered -- "silenced" -- during nested type checking calls).
Start the clean up by moving truncation to the REPL,
since it's not relevant for regular reporting. Perversely, we were checking
truncation all the time, even though it's only on during a repl run.
(Truncation is now always turned off in the repl under -verbose.)
Untangle error resetting on symbols from error reporting (reportAdditionalErrors).
This fixes a nice&subtle bug that caused feature warnings to be suppressed under
`-Xfatal-warnings`:
```
def reportCompileErrors() {
if (!reporter.hasErrors && reporter.hasWarnings && settings.fatalWarnings)
globalError("No warnings can be incurred under -Xfatal-warnings.")
if (reporter.hasErrors) { ... }
else {
// will erroneously not get here if
// `reporter.hasWarnings && settings.fatalWarnings`
// since the `globalError` call above means `reporter.hasErrors`...
allConditionalWarnings foreach (_.summarize())
...
}
}
```
The second `if`'s condition depends on the `globalError` call in the first `if`...

I've seen the reported problem before in the wild. It seems
worthy of a special warning, so long as we advocate Option.apply
as an alternative to `if (x == null) Some(x) else None`.
It is behind -Xlint at the moment, an option that could do with
some promotion.
