      [wasm] Allow storing of arguments count in a safepoint. · 366cddfa
      Michael Starzinger authored 
      This overlays the "arguments count" and the "deoptimization index"
fields within a safepoint entry. It allows for a larger value of
arguments count to be stored in entries that do not contain a
deoptimization index. Currently the arguments count is unused in
TurboFan, but it will be used to handle reference type arguments in
WebAssembly code.

      [Liftoff] Avoid unneeded CacheState Steal · acc4ed88
      Clemens Hammacher authored 
      When finishing a one-armed if, the else state has to be merged into the
end state. We did this before by switching to the else state, then
doing the merge. This CL changes this to avoid the switch.

Drive-by: Add a few missing "const" qualifiers. The style guide forbids
non-const l-value references.
