```
x86 backend: don't read bogus safety flag

Safety is not a global flag that should be enabled or disabled for all
stores - it's lowered by the frontend directly into AIR instruction
semantics. The flag for this is communicated via the `store` vs
`store_safe` AIR instructions, and whether to write 0xaa bytes or not
should be decided in `airStore` and passed down via function parameters.

This commit is a step backwards since it removes functionality but it
aims our feet towards a better mountain to climb.
