Currently, goroutine switches are implemented with libc
getcontext/setcontext functions, which saves/restores the machine
register states and also the signal context. This does more than
what we need, and performs an expensive syscall.
This CL implements a simplified version of getcontext/setcontext,
in assembly, that only saves/restores the necessary part, i.e.
the callee-save registers, and the PC, SP. A simplified version
of makecontext, written in C, is also added. Currently this is
only implemented on Linux/AMD64.

gofrontend repo...
Correct gcc/go/gofrontend/lex.cc and libgo/aclocal.m4 to the versions
in the gofrontend repo, which is supposed to be the master copy.
Remove a few files in libgo that somehow were not deleted in the past.

This avoids linker warnings when linking against glibc, as apparently
arm64 GNU/Linux does not support the ustat system call.
Also update to automake 1.11.6, as that is the new GCC standard.
