Actual regression was introduced in r272668. This revision fixes JS script, but
also regress Cpp case. It manifests with spaces added when template is followed
with array. Bug 30527 mentions case of array as a nested template type
(foo<bar<baz>[]>). Fix is to detect such case and to prevent treating it as
array initialization, but as a subscript case. However, before r272668, this
case was treated simple because we were detecting it as a StartsObjCMethodExpr.
Same was true for other similar case - array of templates (foo<int>[]). This
patch tries to address two problems: 1) fixing regression 2) making sure both
cases (array as a nested type, array of templates) which were entering
StartsObjCMethodExpr branch are handled now appropriately.

Output generated by option -ast-print looks like C/C++ code, and it
really is for plain C. For C++ the produced output was not valid C++
code, but the differences were small. With this change the output
is fixed and can be compiled. Tests are changed so that output produced
by -ast-print is compiled again with the same flags and both outputs are
compared.
Option -ast-print is extensively used in clang tests but it itself
was tested poorly, existing tests only checked that compiler did not
crash. There are unit tests in file DeclPrinterTest.cpp, but they test
only terse output mode.

The current version does not deduplicate equivalent file paths correctly.
For example, a relative path and an absolute path are considered inequivalent.

Reasoning:
- ExpressionParser uses a lot of stack for these, bad in some environments.
- Our formatting algorithm is N^3 and gets really slow.
- The resulting formatting is unlikely to be any good.
- This is probably generated code we're formatting by accident.
We treat these as unparseable, and signal incomplete formatting. 50 is
an arbitrary number, I've only seen real problems from ~150 levels.

Summary:
clang-tidy's modernize-use-auto check uses the SourceRange of a
TypeLoc when replacing the type with auto.
This was producing the wrong result for multi-token builtin types
like long long:
-long long *ll = new long long();
+auto long *ll = new long long();

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

Fixes the following:
BOOL (^aaa)(void) = ^BOOL {
};
The first BOOL's token was getting set to TT_FunctionAnnotationRParen
incorrectly, which was causing an unexpected newline after (^aaa). This
was introduced in r245846.

Summary:
- If a replacement has offset UINT_MAX, length 0, and a replacement text
that is an #include directive, this will insert the #include into the
correct block in the \p Code.
- If a replacement has offset UINT_MAX, length 1, and a replacement text
that is the name of the header to be removed, the header will be removed
from \p Code if it exists.

Summary:
Before when a semicolon was missing after a boolean literal:
a = true
return 1;
clang-format would parse this as one line and format as:
a = true return 1;
It turns out that C++ does not consider `true` and `false` to be literals, we
have to check for that explicitly.

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.
