Tuan Phan fbd4e4684a BACKPORT: Split the old READ_IMPLIES_EXEC workaround from executable 
PT_GNU_STACK now that toolchains long support PT_GNU_STACK marking and
there's no need anymore to force modern programs into having all its
user mappings executable instead of only the stack and the PROT_EXEC
ones.

Disable that automatic READ_IMPLIES_EXEC forcing on x86-64 and
arm64.

Add tables documenting how READ_IMPLIES_EXEC is handled on x86-64, arm
and arm64.

This patch is needed to fix softlock up observed during stress test.
