fix any bad objectiveC syntax coming out of
DeclPrinter. This is on going. Also, introduce a new
PrintPolicy and use it as needed when declaration tag
is to be produced via DeclPrinter.

use clang's formatter. Currently, formatter is used 
to format declaration tags for xml comments. Since formatter
is in flux and its change will break several of the clang comment
tests, only a single tests is formatted using this facility.
Doug has reviewed and approved it for check-in.

We used to format initializers like this (with a sort of hacky implementation):
Constructor()
    : Val1(A),
      Val2(B) {

and now format like this (with a somewhat better solution):
Constructor()
    : Val1(A), Val2(B) {

assuming this would not fit on a single line. Also added tests.

As a side effect we now first analyze whether an UnwrappedLine needs to be
split at all. If not, not splitting it is the best solution by definition. As
this should be a very common case in normal code, not exploring the entire
solution space can provide significant speedup.

This allows for writing tests including line comments easier and more readable.
We will need more of those tests in the future and also line comments are
useful to force line breaks in tests.

avoided.

This required a minor modification of the memoization as now the
"CurrentPenalty" depends on whether or not we break before the current
token. Therefore, the CurrentPenalty should not be memoized but added
after retrieving a value from memory. This should not affect the runtime
behavior.

More specifically:
- Improve formatting of static initializers.
- Fix formatting of lines comments in enums.
- Fix formmating of trailing line comments.

StaticAnalyzer when it's disabled.

Without all those three, the clang binary shrinks (x86_64) from ~36MB
to ~32MB (unstripped).

is not needed.

Doing just 'stat' is faster than 'open/fstat/close'.
This has the effect of cutting down system time for validating the input files of a PCH.

definition, rather than at the end of the definition of the set of nested
classes. We still defer checking of the user-specified exception specification
to the end of the nesting -- we can't check that until we've parsed the
in-class initializers for non-static data members.
