Do not allocate a second "background" alloc id for the main allocation of a static.
...
Instead we re-use the static's alloc id within the interpreter for its initializer to refer to the `Allocation` that only exists within the interpreter.

interpret: rename ReadExternStatic → ExternStatic
This error shows up for reads and writes, so `ReadExternStatic` is misleading.

miri: fail when calling a function that requires an unavailable target feature
...
miri will report an UB when calling a function that has a `#[target_feature(enable = ...)]` attribute is called and the required feature is not available.
"Available features" are the same that `is_x86_feature_detected!` (or equivalent) reports to be available during miri execution (which can be enabled or disabled with the `-C target-feature` flag).
