Implemented tab usage only for indentation (http://llvm.org/PR17363)

Summary:
Changed UseTab to be a enum with three options: Never, Always,
ForIndentation (true/false are still supported when reading .clang-format).
IndentLevel should currently be propagated correctly for all tokens, except for
block comments. Please take a look at the general idea before I start dealing
with block comments.

SourceManager: Open code isInMainFile.

- We really shouldn't compute line numbers for every file that is asked if it's
  the main file, it destroys the lazy computation.
- Invalid locations are no longer accounted to the main file, no other
  functionality change.

Adding pre/post conditions for some Replacement handling functions

The vector version of shiftedCodePosition() requires Replacements to be
in sorted order.

Turned existing comment about sorting for deduplicate() into an exact
post condition.

Avoid the hard-coded limit on the number of typo corrections attempted.

Move some tests from typo-correction.cpp to typo-correction-pt2.cpp
because they were running afoul of the hard-coded limit of 20 typos
corrected. Some of the tests after it were still working due to the
limit not applying to cached corrections and in cases where a non-NULL
MemberContext is passed in to Sema::CorrectTypo.  Most of the moved tests
still passed after being moved, but the test involving "data_struct" had
only been passing because the test had exceeded that limit so a fix for
it is also included (most of the changes to ParseStmt.cpp are shared with
and originated from another typo correction impovement that was split
into a separate commit).
