When I refactored filesystem::path string conversions in
r11-587-584d52b088f9fcf78704b504c3f1f07e17c1cded I failed to update the
mingw-specific code in filesystem::u8path, causing a bootstrap failure.
This fixes it, and further refactors the mingw-specific code along the
same lines as the previous commit. All conversions from UTF-8 strings to
wide strings now use the same helper function, __wstr_from_utf8.

This patch further simplifies way we reffer to global stream. Every function
section has vector of references to global trees which are populated during
streaming. This vector is for some reason divided into field_decls, fn_decls,
type_decls, types, namespace_decls, labels_decls and var_decls which contains
also other things.
There is no benefit for this split except perhaps for making the indexes
bit smaller and possibly better encodable by ulebs. This however does not
pay back and makes things unnecesarily complex.
We may want to re-add multiple tables if we start streaming something else than
trees into the global stream, but that would not work with current
infrastructure anyway.
The patch drops different streams and I checked that it results in reduction of
global stream and apparently very small increase in function streams but it may
be just because I updated tree in between the tests. This will be fixed by
incremental patch.

Diagnosing bad uses of 'return' in coroutines is somewhat
tricky, since the user can use the keyword before we know
that the function is a coroutine (where such returns are not
permitted). At present, we are just doing a check for any
use of 'return' and erroring on that. However, we can't then
pass the function body on, since it will contain unlowered
coroutine trees.
This avoids the issue by dropping the entire function body
under that circumstance. We could do better (for 11) but
this is intended to allow back-port of other fixes to 10.

Testing passed, so I've committed it with those asserts (and thankfully I've
added them!) but it apparently broke Linux kernel build on arm.
The problem is that if the STRING_CST is very short, while the full object
has BLKmode, the short string could very well have
QImode/HImode/SImode/DImode and in that case it wouldn't take the path that
copies the string and then clears the remaining space, but different paths
in which it will ICE because of those asserts and without those it would
just emit wrong-code.
The following patch fixes it by enforcing BLKmode for the string MEM, even
if it is short, so that we copy it and memset the rest.

In the testcase below, the satisfaction value of fn1<int>'s constraint
is INTEGER_CST '1' of type BOOLEAN_TYPE value_type, which is a typedef
to the standard boolean_type_node. But satisfaction_value expects to
see exactly boolean_true_node or integer_one_node, which this value is
neither, causing us to trip over the assert therein.

There are various VSX insns that do the same job as (older) AltiVec

for such insns have the "v" alternative before the "wa" alternative,
which makes the output less readable than possible (since vs32 is v0,
and most insns before or after this insn will be VSX as well).

this patch cleans up tree streaming. The code is prepared to stream nested
trees, but we only handle flat trees. As a result we have quite heavy function
to stream in/out tree reference which is used many times and shows up in
profile.
This patch adds stream_write_tree_ref/stream_read_tree_ref which is used to
stream references to trees that are required to exist in the cache or be
indexable.
The actual implementation is just a first cut. I would like to make it more
compact. We used to stream 2 byte tag (as UHWI) + UHWI representing the index.
Now we stream one UHWI that represent type of reference + index for references
to cache, but still two integers for references to global stream. This is
becaue the abstraction is not very helpful here and I want to clean this up
incrementally.
I would also like to get rid of the ref_p parameters which seems unnecessary for
flat streams.
This reduces around 7% of global stream, 3% when compressed.
More reduction will happen once the format is sanitized a bit.
