qmuntal 3aa2823d8b cmd/internal/link: merge .pdata and .xdata sections from host object files
The Go linker doesn't currently merge .pdata/.xdata sections from the
host object files generated by the C compiler when using internal
linking. This means that the stack can't be unwind in C -> Go.

This CL fixes that and adds a test to ensure that the stack can be
unwind in C -> Go and Go -> C transitions, which was not well tested.

Updates #57302
