Summary:
This adds checks that our diagnostics emit correct ranges in a bunch of cases,
as promised in D41118.
The diagnostics-preamble test is also converted and extended to be a little more
precise.
diagnostics.test stays around as the smoke test for this feature.

Summary:
* For qualified completion (foo::a^)
* unresolved qualifier - use global namespace ("::")
* resolved qualifier - use all accessible namespaces inside the resolved qualifier.
* For unqualified completion (vec^), use scopes that are accessible from the
scope from which code completion occurs.

Global scope is "" (was "")
Top-level namespace scope is "ns::" (was "ns")
Nested namespace scope is "ns::ns::" (was "ns::ns")
This composes more naturally:
- qname = scope + name
- full scope = resolved scope + unresolved scope (D42073 was the trigger)
It removes a wart from the old way: "foo::" has one more separator than "".
Another alternative that has these properties is "::ns", but that lacks
the property that both the scope and the name are substrings of the
qname as produced by clang.
This is re-landing r322996 which didn't build.

Summary:
- we match on USR, and do a field-by-field merge if both have results
- scoring is post-merge, with both sets of information available
(for now, sema priority is used if available, static score for index results)
- limit is applied to the complete result set (previously index ignored limit)
- CompletionItem is only produces for the returned results
- If the user doesn't type a scope, we send the global scope for completion
(we can improve this after D42073)

llvm-svn: 322945
Summary:
This makes performance slower but more predictable (it always processes
every symbol). We need to find ways to make this fast, possibly by precomputing
short queries or capping the number of scored results. But our current approach
is too naive.
It also no longer returns results in a "good" order. In fact it's pathological:
the top N results are ranked from worst to best. Indexes aren't responsible for
ranking and MergedIndex can't do a good job, so I'm pleased that this will make
any hidden assumptions we have more noticeable :-)

Summary:
We now hide the static/dynamic split from the code completion, behind a
new implementation of the SymbolIndex interface. This will reduce the
complexity of the sema/index merging that needs to be done by
CodeComplete, at a fairly small cost in flexibility.

Summary:
This patch removes hidden items from code completion.
Items can be hidden, e.g., by other items in the child scopes.
This patch addresses a particular problem of a duplicate completion
item for the class in the following example:
struct Adapter { void method(); };
void Adapter::method() {
Adapter^
}
We should probably investigate if there are other duplicates in
completion and remove them, possibly adding assertions that it never
happens.

Summary:
This improves a few things:
- the insert -> freeze -> read sequence is now enforced/communicated by the
type system
- SymbolSlab::const_iterator iterates over symbols, not over id-symbol pairs
- we avoid permanently storing a second copy of the IDs, and the
string map's hashtable
The slab size is now down to 21.8MB for the LLVM project.
Of this only 2.7MB is strings, the rest is #symbols * `sizeof(Symbol)`.
`sizeof(Symbol)` is currently 96, which seems too big - I think
SymbolInfo isn't efficiently packed. That's a topic for another patch!
Also added simple API to see the memory usage/#symbols of a slab, since
it seems likely we will continue to care about this.

Summary:
Symbols are not self-contained - it's only safe to hand them out if you
guarantee the lifetime of the underlying data.
Before this lands, I'm going to measure the before/after memory usage of the
LLVM index loaded into memory in a single slab.

Summary:
The goal here is again to make it easier to read and write the tests.
I've extracted `parseTextMarker` from CodeCompleteTests into an `Annotations`
class, adding features to it:
- as well as points `^s` it allows ranges `[[...]]`
- multiple points and ranges are supported
- points and ranges may be named: `$name^` and `$name[[...]]`
These features are used for the xrefs tests. This also paves the way for
replacing the lit diagnostics.test with more readable unit tests, using named
ranges.
Alternative considered: `TestSelectionRange` in clang-refactor/TestSupport
Main problems were:
- delimiting the end of ranges is awkward, requiring counting
- comment syntax is long and at least as cryptic for most cases
- no separate syntax for point vs range, which keeps xrefs tests concise
- Still need to convert to Position everywhere
- Still need helpers for common case of expecting exactly one point/range
(I'll probably promote the extra `PrintTo`s from some of the core Protocol types
into `operator<<` in `Protocol.h` itself in a separate, prior patch...)

- fixed formatOnType which had an equal and opposite off-by-one
- positionToOffset and offsetToPosition both consistently clamp to beginning/end
of file when input is out of range
- gave variables more descriptive names
- removed windows line ending fixmes where there is nothing to fix
- elaborated on UTF-8 fixmes
This will conflict with Eric's D41281, but in a pretty easy-to-resolve way.
