The often used construct {OFStream(stdout)} does not work on Android.

We assumed that if the ErrorThrower is empty after instantiation, then instantiation succeeded and an instance exists which we can return. However, if the start function throws, no instance exists, which caused a crash. With this CL we handle execeptions thrown by the start function correctly.

Mutable globals are stored in the instance differently, so they must be exported differently as well. Also fix a counting bug that occurred when a module contained a global and an imported mutable global (CalculateGlobalOffsets is called twice).

This CL estimates the sizes of the important managed objects in WASM: the decoded module {WasmModule}, the native module that contains code {NativeModule}, and the natively-allocated indirect and import tables {WasmInstanceNativeAllocations}.

As specified in https://tc39.github.io/ecma262/#sec-atomics-wait, the critical section must occur before the load and comparison. This slightly changes the `AtomicsWaitCallback` API, but in a direction that arguably makes it more consistent. As a drive-by fix, reset `node->waiting_` in case there was an exception from the first callback.

In the process: - Add strict ordering of Types so that name mangling is consistent and build time. Previously, the UnionType stored the union's types in a std::set<const Type*>, which did not have a consistent ordering of the types in the set. - Add a int31 type to enable consistency and correctness of handling of 'constexpr int31' values on the C++ side. - By removing the "implicit" keyword for operators, there is now one less difference between operators and calls, another incremental step in unifying operators and calls. - Enable external (i.e. C++-defined) generic specializations - Add CSA support for checking double ElementsKinds, including tests. - Clean up some constexpr/non-constexpr handling of ElementsKinds.

Code generation for stack checks and protected loads produces duplicate loads of the stack pointer and memory base address. Without gvn these turn into actual move operations and sign conversions. Even worse, as turbofan seems to hoist the stack pointer loads to early blocks, I saw a high register pressure and many spills. While there is some compile time cost for gvn, I expect it to be rather low. On the positive side, I see about a 5% performance inprovement for some benchmarks. If compilation time turns out to be an issue, we can still revert. Change-Id: I13be2ace5b27c51c32430d0cb14fbbe8f31fbf6f Reviewed-on: https://chromium-review.googlesource.com/1095335Reviewed-by:

Loading a root generates a kRootRegister-relative load on all architectures but ia32 (where we currently don't have a root register). This is preferable to loading an external reference, which will usually embed an absolute pointer into the generated code, or add an indirection when within an embedded builtin.
