PR77962 shows Go failing on 32-bit x86. This happens because the i386
port requires the split stack prologue to be created before the normal
prologue, and my previous patch changed it to be the other way around.
This patch changes it back. Things will be exactly as before for targets
that do not do shrink-wrapping for separate components. For targets
that *do* support it, all three prologue/epilogue creation functions
will now be called twice for functions that have anything wrapped
separately (instead of just the prologue created twice).
PR bootstrap/77962
* function.c (thread_prologue_and_epilogue_insns): Call all
make_*logue_seq in the same order as traditional. Call them
all a second time if shrink_wrapped-separate.

Trying to get the backend representation of a redefined name can cause a
compiler crash as the compiler can walk over the same statements a
second time. It's also quite unlikely to produce any additional useful
error messages for the user.
Test case follows. I'm not going to bother adding this test case to the
testsuite--crash-on-invalid cases are worth fixing but not worth
continually retesting.

This replaces mem.go and the C runtime_ReadMemStats function with the Go
1.7 mstats.go.
The GCStats code is commented out for now. The corresponding gccgo code
is in runtime/mgc0.c.
The variables memstats and worldsema are shared between the Go code and
the C code, but are not exported. To make this work, add temporary
accessor functions acquireWorldsema, releaseWorldsema, getMstats (the
latter known as mstats in the C code).
Check the preemptoff field of m when allocating and when considering
whether to start a GC. This works with the new stopTheWorld and
startTheWorld functions in Go, which are essentially the Go 1.7
versions.
Change the compiler to stack allocate closures when compiling the
runtime package. Within the runtime packages closures do not escape.
This is similar to what the gc compiler does, except that the gc
compiler, when compiling the runtime package, gives an error if escape
analysis shows that a closure does escape. I added this here because
the Go version of ReadMemStats calls systemstack with a closure, and
having that allocate memory was causing some tests that measure memory
allocations to fail.
