The current aka diagnostics can sometimes leak internal details that
seem more likely to be distracting than useful.  E.g. on aarch64:

  void f (va_list *va) { *va = 1; }

gives:

  incompatible types when assigning to type ‘va_list’ {aka ‘__va_list’} from type ‘int’

where __va_list isn't something the user is expected to know about.
A similar thing happens for C++ on the arm_neon.h-based:

  float x;
  int8x8_t y = x;

which gives:

  cannot convert ‘float’ to ‘int8x8_t’ {aka ‘__Int8x8_t’} in initialization

This is accurate -- and __Int8x8_t is defined by the AArch64 PCS --
but it's not going to be meaningful to most users.

This patch stops the aka code looking through typedefs if all of
the following are true:

(1) the typedef is built into the compiler or comes from a system header

(2) the target of the typedef is anonymous or has a name in the
    implementation namespace

(3) the target type is a tag type or vector type, which have in common that:
    (a) we print their type names if they have one
    (b) what we print for anonymous types isn't all that useful
        ("struct <anonymous>" etc. for tag types, pseudo-C "__vector(N) T"
        for vector types)

The patch does this by recursively looking for the aka type, like the
C++ frontend already does.  This in turn makes "aka" work for distinct type
copies like __Int8x8_t on aarch64, fixing the ??? in aarch64/diag_aka_1.c.

We applied a conservative, but fairly large, hammer to fix PR71767.
However, ideally, we want minimise the number of symbols visible to
ld64 and to match the cases emitted by clang (since that's what ld64
is expecting).  Now we've improved the handling of indirections, we
can make the indirection symbols local when they are in the regular
non-lazy symbol pointers section.  We will continue to make any
indirections in the data section visible (since right now we have no
way to track if a given symbol follows a weak global).
This change makes no difference to handling of labels for constants
(to be revised in a future patch).

There's a mechanical change to a number of tests (allowing 'l' or 'L'
as the indirection symbol prefix).

When we're using the LLVM-based assembler (the default on modern Darwin)
the ordering of stubs and non-lazy symbol pointers is important.

Interleaving the output (current GCC behaviour) leads to crashes which
prevents us from building code with symbol stubs.

To resolve this, we order the output of stubs and symbol indirections:

 1. Any indirections in the data section
 2. Symbol stubs.
 3. Non-lazy symbol pointers.

At present, we still emit LTO sections after these.

This eventually triggers an abort because 8160 is not a sign-extended
QImode value.
