The actual stack unwind code is still in C, but the rest of the code,
notably all the memory allocation, is now in Go. The names are changed
to the names used in the Go 1.7 runtime, but the code is necessarily
somewhat different.
The __go_makefunc_can_recover function is dropped, as the uses of it
were removed in https://golang.org/cl/198770044.

We treated this g as a sibling call to f:
int f (int);
int g (void) { return f (1); }
but not this one:
struct s { int i; };
struct s f (int);
struct s g (void) { return f (1); }
We treated them both as sibcalls on x86 before the first patch for PR36326,
so I suppose this is a regression of sorts from 4.3.
The patch allows function returns to be local aggregate variables as well
as gimple registers.
