clang-format: Fix incorrect indentation.

Before:
aaaaaaaaaa(bbbbbbbbbbbbbbbbbbbbbbbbb.ccccccccccccccccc(
               dddddddddddddddddddddddddddddd));
aaaaaaaaaaa(bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb(
    dddddddddddddddddddddddddddddd));

After:
aaaaaaaaaaa(bbbbbbbbbbbbbbbbbbbbbbbbb.ccccccccccccccccc(
    dddddddddddddddddddddddddddddd));
aaaaaaaaaaa(bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb(
    dddddddddddddddddddddddddddddd));

This was overlooked when interducing the new builder-type call
detection in r189337. Also, some minor reorganization of a test.

Sema: avoid reuse of Exprs when synthesizing operator=

Summary:
Previously, Sema was reusing parts of the AST when synthesizing an assignment
operator, turning it into a AS-dag. This caused problems for the static
analyzer, which assumed an expression appears in the tree only once.

Here I make sure to always create a fresh Expr, when inserting something into
the AST, fixing PR16745 in the process.

Revert r189649 because it was breaking sanitizer bots.
