If test case framing appears in ordinary test output,
then test2json can get confused. If the fake framing is being
saved with t.Logf/t.Errorf/etc then we can already
distinguish it from real framing, and the code did.
It just forgot to write that framing as output (1-line fix).

If you have a package p1 with an xtest (package p1_test)
that imports p2, where p2 itself imports p1, then when
trying to do coverage for p1 we need to make sure to
recompile p2. The problem was that the overall package
import graph looked like:
main -> p1_test -> p2 -> p1
Since we were recompiling p1 with coverage, we correctly
figured out that because p2 depends on a package being
recompiled due to coverage, p2 also needs to be split (forked) to
insert the dependency on the modified p1. But then we used
the same logic to split p1_test and main, with the effect that
the changes to p2 and p1_test and main were lost, since the
caller was still holding on to the original main, not the split version.
Change the code to treat main and p1_test as "already split"
and just update them in place.

findrunnable loops over allp to check run queues *after* it has
dropped its own P. This is unsafe because allp can change when nothing
is blocking safe-points. Hence, procresize could change allp
concurrently with findrunnable's loop. Beyond generally violating Go's
memory model, in the best case this could findrunnable to observe a
nil P pointer if allp has been grown but the new slots not yet
initialized. In the worst case, the reads of allp could tear, causing
findrunnable to read a word that isn't even a valid *P pointer.
Fix this by taking a snapshot of the allp slice header (but not the
backing store) before findrunnable drops its P and iterating over this
snapshot. The actual contents of allp are immutable up to len(allp),
so this fixes the race.

use 2MB stacks on 64-bit Windows. This is the corresponding change to
make 32-bit Windows always use large (1MB) stacks because it's
difficult to detect when Windows applications will call into arbitrary
C code that may expect a large stack.
This is done as a separate change because it's possible this will
cause too much address space pressure for a 32-bit address space. On
the other hand, cgo binaries on Windows already use 1MB stacks and
there haven't been complaints.

My previous fix for issue 23179 was incomplete; it turns out that if
an unnamed parameter is below a specific size threshold, it gets
register-promoted away by the compiler (hence not encountered during
some parts of DWARF inline info processing), but if it is sufficiently
large, it is allocated to the stack as a named variable and treated as
a regular parameter by DWARF generation. Interestingly, something in
the ppc64le build of k8s causes an unnamed parameter to be retained
(where on amd64 it is deleted), meaning that this wasn't caught in my
amd64 testing.
The fix is to insure that "_" params are treated in the same way that
"~r%d" return temps are when matching up post-optimization inlined
routine params with pre-inlining declarations. I've also updated the
test case to include a "_" parameter with a very large size, which
also triggers the bug on amd64.
