This is a reland of 410ca4c50e
Skip new test for unsupported liftoff architecture.
Previously, if there is some unsupported liftoff functions, it fall
through Turbofan but recompilation didn't catch and count it. This CL
fixes it by using requested_tier on finished units.
Avoid to tier down asm.js.
Introduce reached recompilation tier to monitor recompilation progress.

This scenario is where user is at the end of Wasm execution and do
some stepping. Hence, user should be back at Javascript frame. We
can detect that stepping as it exits Wasm Interpreter and prepare
debugging as a step-out-ish in Javascript.

We detect a stepping in Wasm from Javascript into Wasm then prepare
the target function for debugging.
The trick is redirect the target to interpreter and set a 'fake'
breakpoint in the first instruction. Currently we don't need to clear
this 'fake' breakpoint since it won't notify unless user intend to
step in.

Wasm frames are special in that they have a non-integer script id
in inspector. The way we treat script ids currently is a bit of a mess -
our runtime functions expected integer IDs while inspector has string
IDs (which contain integers, except for Wasm frames). This will need to
be cleaned up once more Wasm tests are added.
The meaning of line/column numbers has also changed; the old JS debug
API encoded the function index and byte offset into line/column numbers,
while inspector-based API actually translates into lines/columns in the
disassembly.
