Fix a small bug in the libgo Makefile recipe that constructs the
directory from which to pick up libgcc_s.so ; the gccgo invocation
with -print-libgcc-file-name was missing the flags, which meant that
for -m32 builds we'd see the 64-bit libgcc dir.

This patch extends the C frontend's "knowledge" of the C stdlib within
get_c_name_hint to cover some more macros and functions, covering
a case reported in PR c/81404 ("INT_MAX"), so that rather than printing:
t.c:5:12: error: 'INT_MAX' undeclared here (not in a function); did you mean '__INT_MAX__'?
int test = INT_MAX;
^~~~~~~
__INT_MAX__
we instead print:
t.c:5:12: error: 'INT_MAX' undeclared here (not in a function)
int test = INT_MAX;
^~~~~~~
t.c:5:12: note: 'INT_MAX' is defined in header '<limits.h>'; did you forget to '#include <limits.h>'?
t.c:1:1:
+#include <limits.h>
t.c:5:12:
int test = INT_MAX;
^~~~~~~
It also adds generalizes some of the code for this (and for the "std::"
namespace hints in the C++ frontend), moving it to a new
c-family/known-headers.cc and .h, and introducing a class known_headers.
This currently just works by scanning a hardcoded array of known
name/header associations, but perhaps in the future could be turned
into some kind of symbol database so that the compiler could record API
uses and use that to offer suggestions e.g.
foo.cc: error: 'myapi::foo' was not declared in this scope
foo.cc: note: 'myapi::foo" was declared in header 'myapi/private.h'
(included via 'myapi/public.h') when compiling 'bar.cc'; did you forget to
'#include "myapi/public.h"'?
or somesuch.
In any case, moving this to a class gives an easier way to locate the
hardcoded knowledge about the stdlib.
The patch also adds similar code to the C++ frontend covering
unqualified names in the standard library, so that rather than just
e.g.:
t.cc:19:13: error: 'NULL' was not declared in this scope
void *ptr = NULL;
^~~~
we can emit:
t.cc:19:13: error: 'NULL' was not declared in this scope
void *ptr = NULL;
^~~~
t.cc:19:13: note: 'NULL' is defined in header '<cstddef>'; did you forget
to '#include <cstddef>'?
t.cc:1:1:
+#include <cstddef>
t.cc:19:13:

The C frontend already "knows" about many common functions in
the C standard library:
test.c: In function 'test':
test.c:3:3: warning: implicit declaration of function 'printf' [-Wimplicit-function-declaration]
printf ("hello world\n");
^~~~~~
test.c:3:3: warning: incompatible implicit declaration of built-in function 'printf'
test.c:3:3: note: include '<stdio.h>' or provide a declaration of 'printf'
and which header file they are in.
However it doesn't know about various types and macros:
test.c:1:13: error: 'NULL' undeclared here (not in a function)
void *ptr = NULL;
^~~~
This patch uses the name_hint/deferred_diagnostic machinery to
add hints for missing C standard library headers for some of the
most common type and macro names.
For example, the above becomes:
test.c:1:13: error: 'NULL' undeclared here (not in a function)
void *ptr = NULL;
^~~~
test.c:1:13: note: 'NULL' is defined in header '<stddef.h>'; did you forget to '#include <stddef.h>'?

(lookup_name_fuzzy): Call get_c_name_hint and use it to

* gcc.dg/spellcheck-stdlib.c: New test case.
From-SVN: r254979

This patch uses the name_hint/deferred_diagnostic to provide
a message in the C++ frontend if a macro is used before it is defined
e.g.:
test.c:6:24: error: expected ';' at end of member declaration
virtual void clone() const OVERRIDE { }
^~~~~
;
test.c:6:30: error: 'OVERRIDE' does not name a type
virtual void clone() const OVERRIDE { }
^~~~~~~~
test.c:6:30: note: the macro 'OVERRIDE' had not yet been defined
test.c:15:0: note: it was later defined here
#define OVERRIDE override
It's possible to do it from the C++ frontend as tokenization happens
up-front (and hence the macro already exists when the above is parsed);
I attempted to do it from the C frontend, but because the C frontend only
tokenizes on-demand during parsing, the macro isn't known about until
later.

In various places we use lookup_name_fuzzy to provide a hint,
and can report messages of the form:
error: unknown foo named 'bar'
or:
error: unknown foo named 'bar'; did you mean 'SUGGESTION?
This patch provides a way for lookup_name_fuzzy to provide
both the suggestion above, and (optionally) additional hints
that can be printed e.g.
note: did you forget to include <SOME_HEADER.h>?
This patch provides the mechanism and ports existing users
of lookup_name_fuzzy to the new return type.
There are no uses of such hints in this patch, but followup
patches provide various front-end specific uses of this.

Expanders for Armv8-M nonsecure call unnecessarily clobber r4 despite
the libcall they perform not writing to r4. Furthermore, the
requirement for the branch target address to be in r4 as expected by
the libcall is modeled in a convoluted way in the define_insn patterns:
the address is a register match_operand constrained by the match_dup
for the clobber which is guaranteed to be r4 due to the expander.
This patch simplifies all this by simply requiring the address to be in
r4 and removing the clobbers. Expanders are left alone because
cmse_nonsecure_call_clear_caller_saved relies on branch target memory
attributes which would be lost if expanding to reg:SI R4_REGNUM.
