Do not attempt to rewrite RHS again. Never rewrite a rewritten text!

completes support for C1X anonymous struct/union init features:
* Indexed anonymous member initializers should not be expanded. Doing so makes
little sense and would cause unresolvable semantic ambiguity in valid code
(regression introduced by r69153).
* Subobject initialization of (possibly nested) anonymous members are now
referred to with paths relative to the naming record context, eliminating the
synthesis of incorrect implicit InitListExprs that caused CodeGen to assert.
* Field lookup was missing a null check in IdentifierInfo comparison which
caused lookup for a known (already resolved) field to match the first unnamed
data member it encountered leading to silent miscompilation.
* Subobject paths are no longer built using the general purpose
Sema::BuildAnonymousStructUnionMemberPath(). If any corner cases crop up, we
will now assert earlier in Sema instead of passing invalid InitListExprs
through to CodeGen.
Fixes PR6955, from Alp Toker!

unless it's a non-packed field, in which case it can only increase the
alignment. [[align]] effectively works the same way for well-formed code
(because it's ill-formed for [[align]] to decrease alignment ever).

preambles:
- When we rebuild a precompiled preamble, make sure to disable
skipping anything in the main file; we may have had leftover
preamble-skipping values in the lexer, which leads to very empty
preamble. This is a correctness issue.
- When we rebuild a precompiled preamble, clear out any prior state
in the Diagnostic object. Otherwise, we might think that there
were errors when we were building the preamble itself, and
therefore reject the resulting preamble. This is mainly a
performance issue.
- Don't remove old remappings when digging out the remapping for the
main file. Having the old mappings around does not hurt in the
common case (later remappings will just overwrite them), and is
important when we fail to find a preamble: we don't want to have
removed the remapping, because we'll need it later.

- Fixed some iterator style issues
- Don't process blocks that have been visited already
- Fixed a case where a unreachable block cycle was not reported
- Minor test case changes
- Added one test case from flow-sensitive version of the check. More coming.

considering whether I want to implement the extension that permits the
use of VLA types in a 'new' expression.
