Clusterfuzz generated test cases for narrow Load, CmpExchg nodes in which the index is a word64 expression. This was not handled correctly leading to a malformed graph. Use default lowering for all atomic narrow operations, and add reduced test cases in wasm cctests with the same sequence as the ones generated by binaryen for other I64Atomic operations as well.

Now, the CodeAssembler can annotate Nodes with SourcePositions. SourcePositions themselves get a new mode "external," in which they get a file_id, line and column. The file_id is currently maintained in the isolate, mapping to strings for filenames. Additionally, inlining information is ignored at this point, but in the long run I'd like to recognize calls to different CSA functions as manual inlinings. At this point, if you want to see the results in tools like GDB, you'll need to build without clang, and use the GCC toolchain. GN flag is_clang=false will do the trick.

The test was originally testing the max string length limit, but due to refactoring of Array.join started consuming too much memory, resulting in OOMs on TSAN builds.

In wasm code, we sometimes see the pattern <some 64 bit expression> i32.wrap/i64 i32.load where we generate an instruction to extend the 32 bit offset into a zero extended 64 bit value for the actual load. However, the preceeding truncate already yields a zero extended 32 bit value, so the extra instruction is not needed. Even more, it might get in the way of munching more computation into the final load. This change adds information about the zero extending behavior to the existing optimization that avoids the zero extension.

Ross McIlroy authored
The decision as to whether to optimize an IIFE as oneshot depends on whether it's outer scope is the script scope. During lazy compile, we might have discarded scopes which don't need a context between the IIFE and the script scope, which means we might treat an IIFE as oneshot, even though initial eager compile treated it as non-oneshot. Both bytecode flushing and lazy source positions rely on us generating the same bytecode during lazy compile as eager compile, so we move the decision into the parser where it happens once and is then stored in the SFI for any future lazy compiles.
