[PATCH 13/50] target/i386: Assert LMA for x86_64 user-only

[Richard Henderson]

LMA is a pre-requisite for CODE64, so there is no way to disable it
for x86_64-linux-user, and there is no way to enable it for i386.

Since we're adding an accessor macro, pull the value directly out
of flags when we're not assuming a constant.
