runtime: don't call funcPC from a function
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.

C++: avoid most reserved words as misspelling suggestions (PR c++/81610 and PR c++/80567)
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.

compiler: update iota handling, fix using iota in array length
CL 71750 changed the definition of how iota works. This patch updates
gccgo for the new definition.
We've been mishandling iota appearing in a type that appears in a
const expression, as in `c = len([iota]int{})`. Correct that by copying
type expressions when we copy an expression. For simplicity only copy
when it can change the size of a type, as that is the only case where
iota in a type can affect the value of a constant (I think). This is
still a bunch of changes, but almost all boilerplate.

compiler: don't incorrectly evaluate range variable
The language spec says that in `for i = range x`, in which there is no
second iteration variable, if len(x) is constant, then x is not
evaluated. This only matters when x is an expression that panics but
whose type is an array type; in such a case, we should not evaluate x,
since len of any array type is a constant.
