    The escape analysis support is not yet good enough to avoid escaping
    the argument to funcPC.  This causes unnecessary and often harmful
    memory allocation.  E.g., (*cpuProfile).addExtra can be called from a
    signal handler, and it must not allocate memory.
    
    Move the calls to funcPC to use variables instead.  This was done in
    the original migration to using funcPC, but was not done for newer code.
    
    In one case, in signal handling code, use getSigtramp.

lookup_name_fuzzy can offer some reserved words as suggestions for
misspelled words, helping with "singed"/"signed" typos.

PR c++/81610 and PR c++/80567 report problems where the C++ frontend
suggested "if", "for" and "else" as corrections for misspelled variable
names.

The root cause is that in r247233
  ("Fix spelling suggestions for reserved words (PR c++/80177)")
I loosened the conditions on these reserved words, adding this condition:
   if (kind == FUZZY_LOOKUP_TYPENAME)
to the logic for rejecting words that don't start decl-specifiers, to
allow for "static_assert" to be offered.

This is too loose a condition: we don't want to suggest *any* reserved word
when we're in a context where we don't know we expect a typename.

For the kinds of error-recover situations where we're suggesting
spelling corrections we don't have much contextual information, so it
seems prudent to be stricter about which reserved words we offer
as spelling suggestions; I don't think it makes sense for us to
suggest e.g. "for".

This patch implements that by effectively reinstating the old logic,
but special-casing RID_STATIC_ASSERT, moving the logic to a new
subroutine (in case we want to allow for other special-cases).

I attempted to add suggestions for the various RID_*CAST, to cope
with e.g. "reinterptet_cast" (I can never type that correctly on the
first try), but the following '<' token confuses the error-recovery
enough that the suggestion code isn't triggered.

    Normally we ensure to build a single Btype for identical types.
    We did not do this for methods table of identical interface
    types, however. If there are two identical interface type I, I2,
    they have the same Btype BI, but different Btypes for their
    methods tables, BM and BM2. From the backend's point of view
    only one of them is linked to BI. This can cause inconsitency
    in the backend's type system, like unresolved placeholder. This
    CL ensures we create a single Btype for methods table of
    identical interface type.
