The issue was re-producible with e.g.:
void g()
{
// Type 'foo.' as fast as possible in the next line
}
This led to "foo->" with completion results as if there was no "foo." at
all in that line.
We relied on a correct position for
translationUnit.sourceLocationAtWithoutReparsing(), but the just typed
characters were not yet reparsed. And we do not want to reparse at that
point since takes too long. We already determine the utf8 position for
the dot character, so simply use that instead.
This completes commit 17c1325cc4.

The position of the dot character was determined on an outdated
translation unit.
We queried the translation unit for the source location of the dot
character, but apparently clang_codeCompleteAt() does not update the
source locations for the translation unit. And we do not want to reparse
since this is expensive. Thus, determine the byte position manually by
scanning over the document until the right line/column is reached.

Sometimes you need a very small array which has a size and max size.
QVarLengthArray is simular but has some size and run time overhead and it
has no max size. It will instead malloc. So this array is for very small
collections under 256 values which never allocate and have only a size
overhead of a byte.

SmallString is a very simple utf8 string class. It's purpose is performance.
It uses a short string opimization which provides 31 bytes of heap free
memory to save a 30 bytes long string plus null terminator. If the string
gets larger heap is allocated. The grow strategy is 1.5 to improve reuse
of allocated memory.
It uses optionally constexpr to provide string literals.

1 struct Foo { int member; };
2 void f(Foo *foo)
3 {
4 foo.<REQUEST COMPLETION> // correct '.' to '->' and provide results
5 }
The preferred approach would be to check if "foo" in line 4 is of
pointer type, but there is no suitable cursor (only CompoundStmt) at
that position since the code is usually not yet parsed and thus invalid.
Thus, just run the completion as is. If there are not any results for a
dot completion, re-run the completion with "." exchanged by "->". This
approach is inherently slower than the preferred approach implemented in
the built-in code model.
The following rare cases are not handled:
1) Requesting completion after white space:
Works: foo.<COMPLETE HERE>
Fails: foo. <COMPLETE HERE>
2) Opening a file and requesting completion (ctrl+space) without prior
editing. No editing before triggering completion means that no
unsaved file is generated on the backend side, which is a
requirement for the correction.
