This reduces wasm's ABI on Arm to only using the even-numbered float registers
in anticipation of Liftoff supporting f32 values on the arm32 port. This is due
to Liftoff assuming a one-to-one mapping between double and float registers.
The ABI must be restricted in order to allow Liftoff compiled and Turbofan
compiled functions to call each other. Turbofan continues to use all float
registers internally however.

The test was flaky because it assumed that AllocatedAssemblerBuffer
would eventually return an address within near-call range. Rarely, this
did not happen (within the retry limit), and so the test would crash.

This fix allocates a single, kMaxWasmCodeMemory-sized buffer for the
test, and generates call sequences within that buffer.

waiting_ flag is now set inside a lock to prevent data race. This means
that waiting_ is false when callback is called at start of wait. To deal
with the new behavior, NotifyWake now always tries to Notify and sets
interrupted_ flag which will be handled by any future wait.

See usage in the js-api tests; previously it would have thrown without

That reduces the overhead of ParseAssignmentExpression at the cost of a few
more branches in the possible arrow head paths.

This also fixes the case where an outer scope of an arrow function didn't call eval
but a parameter initializer does. Previously the outer scope was also marked as
calling eval, causing worse performance. (Unlikely to happen though.)
