Some patterns are using '%w2' for immediate operands, which means that a zero
immediate is actually emitted as 'wzr' or 'xzr'. This not only changes an
immediate operand into a register operand but may emit illegal instructions
from legal RTL (eg. ORR x0, SP, xzr rather than ORR x0, SP, 0).

If the compiled program does a shift by a negative amount, combine will
happily work with that, but it shouldn't then do an undefined operation
in GCC itself. This patch fixes the first case mentioned in the bug
report (I haven't been able to reproduce the second case, on trunk at
least).

The resolution of C11 DR#423, apart from doing things with the types
of expressions cast to qualified types which are only in standard
terms observable with _Generic and which agree with how GCC has
implemented _Generic all along, also specifies that qualifiers are
discarded from function return types: "derived-declarator-type-list
function returning T" becomes "derived-declarator-type-list function
returning the unqualified version of T" in the rules giving types for
function declarators. This means that declarations of a function with
both qualified and unqualified return types are now compatible,
similar to how different declarations can vary in whether a function
argument is declared with a qualifier or unqualified type.
This patch implements this resolution. Since the motivation for the
change was _Generic, the resolution is restricted to C11 mode; there's
no reason to consider there to be a defect in this regard in older
standard versions. Some less-obvious issues are handled as follows:
* As usual, and as with function arguments, _Atomic is not considered
a qualifier for this purpose; that is, function declarations must
agree regarding whether the return type is atomic.
* By 6.9.1#2, a function definition cannot return qualified void. But
with this change, specifying "const void" in the declaration
produces the type "function returning void", which is perfectly
valid, so "const void f (void) {}" is no longer an error.
* The application to restrict is less clear. The way I am
interpreting it in this patch is that "unqualified version of T" is
not valid if T is not valid, as in the case where T is a
restrict-qualified version of a type that cannot be restrict
qualified (non-pointer, or pointer-to-function). But it's possible
to argue the other way from the wording.
Bootstrapped with no regressions on x86_64-pc-linux-gnu.
gcc/c:
* c-decl.c (grokdeclarator): For C11, discard qualifiers on
function return type.

* gcc.dg/qual-return-5.c, gcc.dg/qual-return-6.c: New tests.

Implements the discovery phase according the SCC algorithm used in
gc/esc.go. Traverse all functions to find components that are either
trivial or recursive. The discovered function groups will be analyzed
from the bottom-up to allow for an inter-procedural analysis.
