Removes the --ignition-staging flag since it is no longer used
by anything and won't be a shipping configuration. Also removes
ignition_turbo variant from testrunner, since it is now
the same as the turbofan variant.

We did not associate any position to the stack check in the wasm
function prologue, hence a check failed later when trying to map the
non-existent position to the asm.js source position.
With this CL, we add a mapping to the source position table, mapping
the stack check call to byte offset 0 (which is distinct from any valid
instruction position). Also, we add another entry to the asm.js source
position sidetable, mapping byte offset 0 to the start source position
of the function body.
