clang-format: Be slightly more cautious when formatting subsequent lines after a change. With r251474, clang-format could indent the entire rest of the file, if there is a missing closing brace, e.g. while writing code in an editor. Summary: With this change, clang-format stops formatting when either it leaves the current scope or when it comes back to the initial scope after going into a nested one.

[clang-format] Handle trailing comment sections in import statement lines Summary: This patch updates the handling of multiline trailing comment sections in import statement lines to make it more consistent with the case in general. This includes updating the parsing logic to collect the trailing comment sections and the formatting logic to not insert escaped newlines at the end of comment lines in import statement lines. Specifically, before this patch this code: ``` #include <a> // line 1 // line 2 ``` will be turned into two unwrapped lines, whereas this code: ``` int i; // line 1 // line 2 ``` is turned into a single unwrapped line, enabling reflowing across comments. An example where the old behaviour is bad is when partially formatting the lines 3 to 4 of this code: ``` #include <a> // line 1 // line 2 int i; ``` which gets turned into: ``` #include <a> // line 1 // line 2 int i; ``` because the two comment lines were independent and the indent was copied.

clang-format: NFC. Move testing of selective formatting to a separate file. This is a first step for splitting the huge FormatTest.cpp into separate files to make it easier to find specific tests. llvm-svn: 239730
