      [builtins] Migrate String.fromCharCode to TurboFan code stub. · 7554360f
      bmeurer authored
      When we moved the String.fromCharCode builtin to C++, we slightly
      regressed the fast single character code argument case. Recovered some
      of the performance by implementing the builtin using the TurboFan
      CodeStubAssembler.
      
      Drive-by-fix: Make sure the stack trace from the implicit ToNumber
      conversion in String.fromCharCode includes the builtin by adding a
      regression test for that.

      [turbofan] Add FixedArray peephole optimizations to CodeStubAssembler · cbdb3738
      danno authored
      Previously, CodeStubAssembler macros performing FixedArray element accesses had
      to compute offsets to elements explicitly with a fair amount of duplicated
      code. Furthermore, any peephole optimizations that could produce better code--
      like recognizing constant indices or combining array index computation with Smi
      untagging--were also duplicated.
      
      This change factors the code to compute FixedArray index offsets into a common
      routine in the CodeStubAssembler that applies standard peephole optimizations to
      all accesses. In order to do this, it also introduces limited introspection into
      the up-until-now opaque Node* type exported from code-assembler.h, allowing
      Nodes to be queried whether they are constant and extracting their constant
      value in that case.

      [turbofan] Introduce TruncateTaggedToWord32 simplified operator. · 0231a7ef
      bmeurer authored
      This allows us to get rid of the "push TruncateFloat64ToInt32 into Phi"
      trick that was used in the MachineOperatorReducer to combine the
      ChangeTaggedToFloat64 and TruncateFloat64ToInt32 operations. Instead of
      doing that later, we can just introduce the proper operator during the
      representation selection directly.
      
      Also separate the TruncateFloat64ToInt32 machine operator, which had two
      different meanings depending on a flag (either JavaScript truncation or
      C++ style round to zero). Now there's a TruncateFloat64ToWord32 which
      represents the JavaScript truncation (implemented via TruncateDoubleToI
      macro + code stub) and the RoundFloat64ToInt32, which implements the C++
      round towards zero operation (in the same style as the other WebAssembly
      driven Round* machine operators).
