This fast path works for ASCII-only strings and is similar to the existing fast-path in C++. Important differences: - The locale check is done at Turbofan optimization time instead of at runtime - Use tables of size 256 instead of 128 to save a bounds-check when handling one-byte strings. - It first performs an equality check that's optimized for detecting inequality quickly by comparing the strings from both ends. If the equality check succeeds, we are done. Otherwise chances are high that the strings differ according to collation level L1 already. Therefore, we first do an L1 check and perform the L3 check only when L1 didn't find a difference. This is based on the assumption that few strings are identical except for different capitalization. - Use the Torque version of string flattening instead of the runtime version.

On 32-bit architectures, we need to run Int64Lowering on the inlinee code to make it compatible with the caller code. Since Int64Lowering now runs while a GraphReducer is active, only one of them can use node marks to store node states. Therefore, we move the Int64Lowering node states to an internal map.

Move the source code position for classes to the point where the block context has already been created. Previously, there would be a mismatch between the context and the scope when using the ScopeIterator. We paused at a point where, according to the source position, we already are in a class scope, but according to the bytecode (context), we would not yet have created the block context for the class.

Implement f32x4.qfma, f32x4.qfms, f64x2.qfma, f64x2.qfms. These were already implement in macro-assembler-x64, so move the implementation to shared-macro-assembler. x64 has a macro list in fma-instr, copy this to ia32, and then use this macro list to define existing vfma{ss,sd} instructions in assembler-ia32. Disassembly support is intentionally omitted in this patch, I will add this in a follow-up. The currently disassembly in x64 is quite verbose and I would like to make use of macro-list but it requires breaking up the macro list into smaller parts, so I will do that refactoring for both ia32 and x64 in the follow-up.

These helper macros declare the same variable (asm_code_comment), when used in 2 scopes (one inside another), we get a shadow variable. In all the current usages, we always have a ASM_CODE_COMMENT in the outer scope (which adds a comment with the function name), and in the inner scope uses a string. It is sufficient to fix these cases by giving the first case (function name) a different variable name.

This CL refactors how the first byte(s) of the input are used to set internal configuration, like which compiler to use and whether Liftoff will be used as reference instead of the interpreter. We now always use exactly one byte, and use it for all internal configuration. If more bits are needed in the future we can either extend to two bytes, or use the same bits for multiple things, while avoiding to lose coverage of all interesting configurations. For now, we use the first byte to derive - which compiler to use per function, - whether to use Liftoff as reference, and - (new) whether to globally enable the mid-tier register allocator.
