Summary:
The current version does not deduplicate equivalent file paths correctly.
For example, a relative path and an absolute path are considered inequivalent.
Comparing FileEnry addresses these issues.

Summary:
Now two replacements are considered order-independent if applying them in
either order produces the same result. These include (but not restricted
to) replacements that:
- don't overlap (being directly adjacent is fine) and
- are overlapping deletions.
- are insertions at the same offset and applying them in either order
has the same effect, i.e. X + Y = Y + X if one inserts text X and the
other inserts text Y.
Discussion about this design can be found in D24717

Summary:
Extend `tooling::Replacements::add()` to support adding order-independent replacements.
Two replacements are considered order-independent if one of the following conditions is true:
- They do not overlap. (This is already supported.)
- One replacement is insertion, and the other is a replacement with
length > 0, and the insertion is adjecent to but not contained in the
other replacement. In this case, the replacement should always change
the original code instead of the inserted text.

the diagnostics options were already parsed by the "Driver".
For tools using clang::Tooling, the diagnostics argument were not parsed.

This patch introduced the ability to decide at runtime whether to parse
JSON compilation database command lines using Gnu syntax or Windows
syntax. However, there were many existing unit tests written that
hardcoded Gnu-specific paths. These tests were now failing because
the auto-detection logic was choosing to parse them using Windows
rules.
This resubmission of the patch fixes this by introducing an enum
which defines the syntax mode, which defaults to auto-detect, but
for which the unit tests force Gnu style parsing.

Summary:
rL277342 made RecursiveASTVisitor visit lambda capture initialization
expressions (these are the Exprs in LambdaExpr::capture_inits()).
jdennett identified two issues with rL277342 (see comments there for details):
- It visits initialization expressions for implicit lambda captures, even if
shouldVisitImplicitCode() returns false.
- It visits initialization expressions for init captures twice (because these
were already traveresed in TraverseLambdaCapture() before rL277342)
This patch fixes these issues and moves the code for traversing initialization
expressions into TraverseLambdaCapture().
This patch also makes two changes required for the tests:
- It adds Lang_CXX14 to the Language enum in TestVisitor.
- It adds a parameter to ExpectedLocationVisitor::ExpectMatch() that specifies
the number of times a match is expected to be seen.

Previously, we would search through all replacements when inserting a
new one to check for overlaps. Instead, make use of the fact that we
already have a set of replacments without overlaps to find the potential
overlap with lower_bound.

Summary:
Lambda capture initializations are part of the explicit source code and
therefore should be visited by default but, so far, RecursiveASTVisitor does not
visit them.
This appears to be an oversight. Because the lambda body needs custom handling
(calling TraverseLambdaBody()), the DEF_TRAVERSE_STMT for LambdaExpr sets
ShouldVisitChildren to false but then neglects to visit the lambda capture
initializations. This patch adds code to visit the expressions associated with
lambda capture initializations.

Summary:
- Implement clang::tooling::Replacements as a class to provide interfaces to
control how replacements for a single file are combined and provide guarantee
on the order of replacements being applied.
- tooling::Replacements only contains replacements for the same file now.
Use std::map<std::string, tooling::Replacements> to represent multi-file
replacements.
- Error handling for the interface change will be improved in followup patches.

- In functions with try { } catch { }, only the try block would be
skipped, not the catch blocks
- The template functions would still be parsed.
- The initializers within a constructor would still be parsed.
- The inline functions within class would still be stored, only to be
discared later.
- Invalid code with try would assert (as in "int foo() try assert_here")
This attempt to do even less while skipping function bodies.

This is a commonly useful feature to have, and we have implemented it
multiple times with different kinds of bugs. This implementation
centralizes the idea in a set of functions that we can then use from the various
tools.
Reverts r262234, which is a revert of r262232, and puts the functions
into FOrmat.h, as they are closely coupled to clang-format, and we
otherwise introduce a cyclic dependency between libFormat and
libTooling.

An implicit copy ctor creates loop VarDecls that hang off CXXCtorInitializer.
RecursiveASTVisitor used to not visit them, so that they didn't show up in the
parent map used by ASTMatchers, causing asserts() when the implicit
DeclRefExpr() in a CXXCtorInitializer referred to one of these VarDecls.

One problem in clang-tidy and other clang tools face is that there is no
way to lookup an arbitrary name in the AST, that's buried deep inside Sema
and might not even be what the user wants as the new name may be freshly
inserted and not available in the AST.
A common use case for lookups is replacing one nested name with another
while minimizing namespace qualifications, so replacing 'ns::foo' with
'ns::bar' will use just 'bar' if we happen to be inside the namespace 'ns'.
This adds a little helper utility for exactly that use case.

Adds `addTargetAndModeForProgramName`, a utility function that will add
appropriate `-target foo` and `--driver-mode=g++` tokens to a command
line for driver invocations of the form `a/b/foo-g++`. It is intended to
support tooling: for example, should a compilation database record some
invocation of `foo-g++` without these implicit flags, a Clang tool may
use this function to add them back.
