This fixes exception creation (by the WebAssembly throw operation) so that it is not observable by JavaScript. Internal properties are now stored with symbol names instead of string names, which also prevents them from being accessed or monkey-patched directly by JavaScript.

WebAssembly.Instantiate would silently fail when the passed in memory object did not have guard regions even though the compiled module assumes so.

In general, whether an error thrown from a script will be muted is passed as (part of) ScriptOriginOptions when the script is compiled. Currently, when eval is called, that information is not given, and it uses the default options (IsSharedCrossOrigin = false, IsOpaque = false). Give it the options for the script in which eval is called.

The previous typing rules for ToNumeric and ToNumber didn't match on the NonBigIntPrimitive input set, which causes trouble when we morph ToNumeric nodes into ToNumber nodes, and generally lead to worse typings in the graph, and thus worse code generation. This change improves the existing typing rules and turns ToNumber into a chokepoint again.

The isolate can be efficiently loaded through other means: either as a root-relative load (if embedded builtins are enabled), or as an embedded external reference (i.e. the absolute pointer is included in the instruction stream) otherwise. The generated code should be at least as fast as previously. On x64 (with embedded builtins): Before: // Register moves in prologue: 0x7f47a6b4860a a 488955e0 REX.W movq [rbp-0x20],rdx // And the load from a stack slot at each use-site. 0x7f47a6b486f2 f2 488b7de0 REX.W movq rdi,[rbp-0x20] After: // Each use-site just loads a root-relative offset. 0x7f1645fcc6ce ee 498dbd38ffffff REX.W leaq rdi,[r13-0xc8] On ia32 (no embedded builtins), before: 0x5c608930 10 8955f0 mov [ebp-0x10],edx 0x5c6089fb db 891424 mov [esp],edx After: 0x41d0898d 8d b80033b156 mov eax,0x56b13300 Removal reduces register pressure, and frees up ebx as the root register on ia32. Note that the set of allocatable registers was only reduced on ia32 to exclude the root register.

When v8_enable_embedded_bytecode_handlers is true, initialize the bytecode dispatch table from the builtins table. Also stops creating the handlers more than once as the SetupInterpreter will now always do nothing even when not starting from a snapshot. In the short term, with the flag enabled all the bytecode handlers are eagerly deserialized. Finally, the bytecode handlers are marked as non-isolate independent to prevent them being embedded in the binary until they can be converted.
