Change Details

Fix message arguments handling introduced in rC332582. Current formatting: ``` [[obj aaaaaaaaaaaaaaaaaaaaaa:42] aaaaaaaaaaaaaaaaaaaaaaaaaaaaa:42 bbbbbbbbbbbbbbbbbbbbb:42 dddddddddddddddddddddd:42]; ``` After this fix: ``` [[obj aaaaaaaaaaaaaaaaaaaaaa:42] aaaaaaaaaaaaaaaaaaaaaaaaaaaaa:42 bbbbbbbbbbbbbbbbbbbbb:42 dddddddddddddddddddddd:42]; ```

Reapply reverted changes from D46879. Currently BreakBeforeParameter is set to true everytime message receiver spans multiple lines, e.g.: ``` [[object block:^{ return 42; }] aa:42 bb:42]; ``` will be formatted: ``` [[object block:^{ return 42; }] aa:42 bb:42]; ``` even though arguments could fit into one line. This change fixes this behavior. Test Plan: make -j12 FormatTests && tools/clang/unittests/Format/FormatTests
