clang-format: Fix tests after recent change to ObjC block formatting.

llvm-svn: 220376

Fixes formatting of empty blocks.

We now only put empty blocks into a single line, if all of:
- all tokens of the structural element fit into a single line
- we're not in a control flow statement

Fixes formatting of empty blocks.

We now only put empty blocks into a single line, if all of:
- all tokens of the structural element fit into a single line
- we're not in a control flow statement

Note that we usually don't put record definitions into a single line, as
there's usually at least one more token (the semicolon) after the
closing brace. This doesn't hold when we are in a context where there is
no semicolon, like "enum E {}".

There were some missing tests around joining lines around the corner
cases of the allowed number of columns, so this patch adds some.

Do not add newline in empty blocks.

void f() {}
now gets formatted in one line.

Improvements to function type and ObjC block formatting.

A<void ()>;
int (*b)(int);

A<void(

Improvements to function type and ObjC block formatting.

Before: int (^myBlock) (int) = ^(int num) {}
A<void ()>;
int (*b)(int);

After: int (^myBlock)(int) = ^(int num) {}
A<void()>;
int(*b)(int);

For function types and function pointer types, this patch only makes
the behavior consistent (for types that are keywords and other types).
For the latter function pointer type declarations, we'll probably
want to add a space after "int".

Also added LangOpts.Bool = 1, so we handle "A<bool()>" appropriately
Moved the LangOpts-settings to a public place for use by tests
and clang-format binary.

Fix ObjC block declarations.

Before: int ( ^ Block1) (int, int) = ^ (int i, int j)
After: int (^Block1) (int, int) = ^(int i, int j)

Various fixes to clang-format's macro handling.

Some of this is still pretty rough (note the load of FIXMEs), but it is
strictly an improvement and fixes various bugs that were related to
macro processing but are also imporant in non-macro use cases.

Specific fixes:
- correctly puts espaced newlines at the end of the line
- fixes counting of white space before a token when escaped newlines are
present
- fixes parsing of "trailing" tokens when eof() is hit
- puts macro parsing orthogonal to parsing other structure
- general support for parsing of macro definitions

Due to the fix to format trailing tokens, this change also includes a
bunch of fixes to the c-index tests.

Temporary fix of tests to make buildbots happy.

Permanent solution coming up after checking back with Fariborz/Douglas.

Add objective-C style formatting to clang format and
use it to format xml declaration tags.

This is the libclang patch providing minimal API to
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.
