Go patch committed: copy signal code from Go 1.7 runtime

This patch to the Go frontend and libgo copies the signal code from the Go 1.7 runtime. This adds a little shell script to auto-generate runtime.sigtable from the known signal names. This forces the main package to always import the runtime package. Otherwise some runtime package global variables

[PATCH] Fix PR 78243 on PowerPC

Aaron Sawdey has been running the GCC testsuite on the power9 simulator and he noticed that: gcc.c-torture/execute/pr68532.c does not run, and opened bug 78243 for this failure. Now, if you compile pr68532 with normal options (-O2/-O3 and -mcpu=power8 or -mcpu=power9) it works because wi
