[PATCH, i386] PR61360: Do not update "enabled" attribute during lra and reload passes

This patch fixes PR 61360.

The attribute "enabled" should actually be used enable/disable alternative based on sub-targets.
In this pattern, it gets used across passes too. 
However, modifying this attribute in LRA pass is not something it is meant for.
This patch allows enabling/disabling the attribute when optimizing for size, but not during lra pass or reload pass.

Bootstrap passes.
OK for upstream?
