Tess Strickland a43d3cb993 [vm/compiler] Use CombineHashes/FinalizeHash methods in intrinsifier. 
AsmIntrinsifier::OneByteString_getHashCode now uses the CombineHashes
and FinalizeHash Assembler methods introduced in 49f998dc31.

To avoid having to check for 0 again after masking the result of
FinalizeHash to fit the desired bit size, we create a more general
FinalizeHashForSize that also takes the desired bit size of the result.

The intrinsified versions for ARM/ARM64/RISCV are also modified to
remove the special casing for the empty string, and instead just check
the size of the string against the loop counter at the start of the
loop, similarly to X64/IA32. This is less efficient for the empty
string case, but avoids the need to create a version of FinalizeHash
that elides the zero check.

TEST=ci

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
