We are currently storing compilation errors in the individual compilation units and pass it to the ErrorThrower during finishing. This CL changes that to store errors on the CompilationState directly. From there, it is propagated to the ErrorThrower in the compilation state callback. This removes more work from the finisher task and slims down the WasmCompilationUnits.

For NumberMin and NumberMax we don't need to go to Float64 when the inputs are known to be in SafeInteger range, instead we can go to Word64 on 64-bit architectures. This is preliminary work for the huge DataView support, since we'll utilize NumberMax in that case to clamp the limit for the bounds check.

The "grow_memory" opcode was renamed to "memory.grow", and the spec repo was updated to use kExprMemoryGrow internally instead of kExprGrowMemory (https://github.com/WebAssembly/spec/pull/720). This CL does the same change for v8. Drive-by: Rename "current_size" to "memory.size", and a minor cleanup in wasm-graph-builder.js to bring it in line with the version in the js-api tests in the spec repo.

This fixes the fall-back case when parsing a multiplicative expression where the lookahead found a '-' token followed by an unsigned token, but no '*' token is following. We cannot rewind both tokens, but still need to make sure that a full multiplicative expression is parsed.

The Counters are not specific to compilation units, they just happen to be used in WasmCompilationUnit::ExecuteCompilation. Remove it from the compilation unit and pass it explicitly where needed. This saves another field on the compilation units.

The bug was that PreParser detected a stack overflow and an unidentifiable error, and we tried to re-parse the same code. However, the stack overflow flag was still set, and that messed up error handling in the Parser.

This allows very large arrays being joined to incrementally, on-demand allocate the internal buffer. Previously, join would allocate the buffer upfront and all at once. Large, sparse arrays will use less memory.
