Documentation tweaks for internal-fn-related optabs
As Bernd requested, this patch adds "This pattern cannot FAIL" to the
documentation of optabs that came to be mapped to interal functions.
For consistency I did the same for optabs that were already being
used for internal functions.
Many of the optabs weren't documented in the first place, so I added
entries for the missing ones. Also, there were some inaccuracies in
the documentation of the rounding optabs. The bitcount optabs said
that operand 0 has mode @var{m} and that operand 1 is under target
control, whereas it should be the other way around.

Add an rsqrt_optab and IFN_RSQRT internal function
All current uses of builtin_reciprocal convert 1.0/sqrt into rsqrt.
This patch adds an rsqrt optab and associated internal function for
that instead. We can then pick up the vector forms of rsqrt automatically,
fixing an AArch64 regression from my internal_fn patches.
With that change, builtin_reciprocal only needs to handle target-specific
built-in functions. I've restricted the hook to those since, if we need
a reciprocal of another standard function later, I think there should be
a strong preference for adding a new optab and internal function for it,
rather than hiding the code in a backend.
Three targets implement builtin_reciprocal: aarch64, i386 and rs6000.
i386 and rs6000 already used the obvious rsqrt<mode>2 pattern names
for the instructions, so they pick up the new code automatically.
aarch64 needs a slight rename.
mn10300 is unusual in that its native operation is rsqrt, and
sqrt is approximated as 1.0/rsqrt. The port also uses rsqrt<mode>2
for the rsqrt pattern, so after the patch we now pick it up as a native
operation.
Two other ports define rsqrt patterns: sh and v850. AFAICT these
patterns aren't currently used, but I think the patch does what the
authors of the patterns would have expected. There's obviously some
risk of fallout though.
Tested on x86_64-linux-gnu, aarch64-linux-gnu, arm-linux-gnueabihf

Fix TYPE_MAIN_VARIANT construction for arrays of qualified typedefs (PR c/68162).
PR c/68162 reports a spurious warning about incompatible types
involving arrays of const double, constructed in one place using a
typedef for const double and in another place literally using const
double.
The problem is that the array of the typedef was incorrectly
constructed without a TYPE_MAIN_VARIANT being an array of unqualified
elements as it should be (though it seems some more recent change
resulted in this producing incorrect diagnostics, likely the support
for C++-style handling of arrays of qualified type). This patch fixes
the logic in grokdeclarator to determine first_non_attr_kind, which is
used to determine whether it is necessary to use the TYPE_MAIN_VARIANT
of the type in the declaration specifiers.
However, fixing that logic introduces a failure of
gcc.dg/debug/dwarf2/pr47939-4.c, a test introduced along with
first_non_attr_kind. Thus, it is necessary to track the original
qualified typedef when qualifying an array type, to use it rather than
a newly-constructed type, to avoid regressing regarding typedef names
in debug info. This is done along lines I suggested in
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=47939#c6>: track the
original type and the number of levels of array indirection at which
it appears, and, in possibly affected cases, pass extra arguments to
c_build_qualified_type (with default arguments to avoid needing to
pass those extra arguments explicitly everywhere). Given Richard's
recent fix to dwarf2out.c, this allows the C bug to be fixed without
causing debug information regressions.
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

fix invalid bounds on array refs
While enabling graphite in -O3 we found a Fortran testcase that fails
because the max of the type domain is -1. We used to add that as a constraint
to the elements accessed by the array, leading to a unfeasible constraint:
0 <= i <= -1. Having that constraint, drops the data reference as that says
that there are no elements accessed in the array.
