When comparing a symbol to istself using <, <=, > or >= we need to
throw a TypeError. This is correctly handled in the runtime function
so if we are comparing a symbol fall back to use the runtime.

Tail calls are matched on the graph, with a dedicated tail call
optimization that is actually testable. The instruction selection can
still fall back to a regular if the platform constraints don't allow to
emit a tail call (i.e. the return locations of caller and callee differ
or the callee takes non-register parameters, which is a restriction that
will be removed in the future).

Also explicitly limit tail call optimization to stubs for now and drop
the global flag.

When we preprocess stack traces, we turn code pointer and offset to
source position, and store it in place of code pointer as smi.

Preprocessing stack traces is currently disabled due to issue 4065.

This introduces a simplified allocation operator which can be used to
model inline allocations in TurboFan. It is currently used for context
allocations, but still disabled because change lowering introduces
floating allocations outside the effect chain that interfere.
