[llvm] [X86AsmParser] IntelExpression: End of Statement should check for valid end state (PR #95677)

[via llvm-commits]

https://github.com/v01dXYZ created https://github.com/llvm/llvm-project/pull/95677

The following commit bfb7099eeb9b6f62510b1db0cb93a8c3cfa68236 added a special case for End of Statement that doesn't check if the state machine is rightfully in a state where ending is valid.

This PR suggest to revert this change to make `EndOfStatement` processed as any other tokens that are not consumable by the state machine.
