Why is the stack for signal delivery not allowed to be in a
SkFileC segment, such as an array in .data or .bss?

If the address is already mapped, then in coregrind/m_signals.c
function VG_(extend_stack) insists on SkAnonC; or SkResvn
(with SkAnonC following) if the address is not already mapped.

Especially if register_stack() is called beforehand with an interval
covers the address, then SkFileC should be allowed.
