Reland [wasm] Allow the initialization of a single compilation unit
Tsan figured out that I called compilation_units_.empty() outside a
lock.
Original message:
This CL adds a new function {InitializeCompilationUnit} to initialize
a single compilation unit and not just all compilation units at once.
This is necessary for streaming compilation eventually. This also
required some refactoring on how the working queue for compilation units
works. Previously the synchronization was done with an atomic counter,
now it is done with a lock. Note that the code to finish compilation
of a module still only works if the working queue gets only empty when
all work is done. I plan to change this in a different CL.
Since the code would not be tested without streaming compilation, I added
an experimental flag and a test to test the new code.
