Make the parser handle references to "this" as unresolved variables, so the
same logic as for the rest of function parameters is used for the receiver.
Minor additions to the code generation handle copying the receiver to the
context, along with the rest of the function parameters.
Based on work by Adrian Perez de Castro <aperez@igalia.com>.

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.

By recording invocations of these builtins that can return -0, we now learn to not emit Crankshaft code that only handles integer results, avoiding deopt loops.

These macros are not needed anymore, so there's no point in supporting
them.

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.

usage: This tool analyzes the commit range between <of> and <until>. It finds commits which belong together e.g. Implement/Revert pairs and Implement/Port/Revert triples. All supplied hashes need to be from the same branch e.g. master.

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.

Please prepare the chromium side tests before a reland.
