This adds an additional V8 API to get the backing store of an array buffer. Unlike the existing API, the backing store comes wrapped in a std::shared_ptr, making lifetime management with the embedder explicit. This obviates the need for the old GetContents() and Externalize() APIs, which will be deprecated in a future CL.

Added tests for the scenario when the fillers would be evacuated within the new space and when they would be promoted into the old space. The fix is to treat the deferred handles the same as the local ones: call FixStaleLeftTrimmedHandlesVisitor for them.

Quasi Fused Multiply-Add and Quasi Fused Multiply-Subtract performs, on floats, a + b * c and a - b * c respectively. When there is only a single rounding, it is a fused operation. Quasi in this case means that the result can either be fused or not fused (two roundings), depending on hardware support. It is tricky to write the test because we need to calculate the expected value, and there is no easy way to express fused or unfused operation in C++, i.e. we cannot confirm that float expected = a + b * c will perform a fused or unfused operation (unless we use intrinsics). Thus in the test we have a list of simple checks, plus interesting values that we know will produce different results depending on whether it was fused or not. The difference between 32x4 and 64x2 qfma/qfms is the type, and also the values of b and c that will cause an overflow, and thus the intermediate rounding will affect the final result. The same array can be copy pasted for both types, but with a bit of templating we can avoid that duplication.

WASM only supports Little-endian byte ordering and we need a mechanism to reverse the ordering efficiently on Big-endian machines. Up until now this was done using TF graphs within wasm-compiler. The new approach allows for having more machine level optimizations by introducing the new "kSimd128ReverseBytes" opcode which gets executed only on Big-endian machines.

On-heap typed arrays contain HeapObject value in |base_pointer| field and an offset in |external_pointer| field. When pointer compression is enabled we want to combine decompression with the offset addition. In order to do that we add an isolate root to the external_pointer value and therefore the data pointer computation can is a simple addition of a (potentially sign-extended) |base_pointer| loaded as Tagged_t value and an |external_pointer| value.

The serialization step in the pipeline gets an initial zone, and thus far, it's allocated all of it's hinting information in that zone. However, much of this comes from stepping into calls and walking the bytecode of the called function. Once we finished recursing into a call, we should be able to throw all those hints away -- they've served their purpose, and the "output" of their work is a set of new objects made visible to the broker. Therefore, we should create and destroy a child zone. On a run of typescript, this reduces absolute max (high water mark) allocation of the serialization phase from 10 MB to 5 MB.

In the mjsunit/wasm/asm-wasm-f32 test, {IsValid} caused 10% of the overall runtime. In absolute numbers, {IsValid} wasm called more than 6.000.000.000 times. I moved the calls to {IsValid} from before-use to after-modification. I removed the calls in {Combine} and {Remove}, because these operations cannot create an invalid CPURegList. These changes reduce the number of calls to {IsValid} to about 100.000.000 in the test mentioned above, and saves for that test about 10 seconds out of before 2 minutes absolute runtime.

This is a first step towards being able to share the same script for multiple {WasmModuleObject} objects. In general it should be possible for the inspector to debug (i.e. disassemble, set breakpoints) multiple modules if they all have the same URL (and the same wire bytes). These are the same conditions under which we can canonicalize the modules to be based on the same underlying {NativeModule} as well. Hence it makes sense to establish a link from {Script} to {NativeModule} in this CL. Subsequent CLs will eventually deprecate the {wasm_module_object} field.

Runtime_CreateRegExpLiteral pretends to handle the case where we already have a boilerplate but the code just passes an empty handle to JSRegExp::Copy. This CL replaces the code with a CHECK that the boilerplate doesn't exist. A few mostly cosmetic changes along the way.
