This JSAsyncFunctionObject represents the implicit generator object inside of async functions, and also holds the outer promise for the async functions. This in turn allows us to get rid of the .promise in the Parser / BytecodeGenerator completely, and will make it possible to build zero-cost async stack traces independent of the concrete synchronous part of the stack frame (which currently breaks in Node.js). In the bytecode all the async function operations now take this new JSAsyncFunctionObject instead of passing both the .generator_object and the .promise, which further simplifies and shrinks the bytecode. It also reduces the size of async function frames, potentially making the suspend/resume cheaper. This also changes `await` to use intrinsics instead of calling to special JSFunctions on the native context, and thus reduces the size of the native contexts. Drive-by-fix: Introduce a dedicated JSCreateAsyncFunctionObject operator to TurboFan.

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.

These two builtins are a special case in that their calling convention must be kept in-sync since they are both generated from Generate_CallOrConstructVarargs. ConstructVarargs in particular used all available registers. In order to free ebx, the calling convention is changed to pass the last argument on the stack. As part of this change, the order of the last two arguments is swapped since the stack parameter must be tagged.

This adds support for unaligned load/store access to the DataView backing store and uses byteswap operations to fix up the endianess when necessary. This changes the Word32ReverseBytes operator to be a required operator and adds the missing support on the Intel and ARM platforms (on 64-bit platforms the Word64ReverseBytes operator is also mandatory now). This further improves the performance on the dataviewperf.js test mentioned in the tracking bug by up to 40%, and at the same time reduces the code complexity in the EffectControlLinearizer.

This is the port of concurrent jump table patching support to ARM. It extends the corresponding stress test and changes the encoding of code targets in jump table slots to use constant pool entries.

We instantiate the JumpTableAssembler in patching mode (i.e. directly on existing code without an intermittent buffer). In this mode it is not possible to record reloc information. This makes sure we no longer just blindly write into the non-existing buffer.

This CL puts off-heap targets (i.e. code addresses for embedded builtins) in the constant pool on ARM. We are landing this CL to evaluate impact on benchmarks and code size, and expect to revert it once we have gathered that data.
