[JSC] Enable LLInt ASM interpreter on X64 and ARM64 in non JIT configuration
​https://bugs.webkit.org/show_bug.cgi?id=189778

Reviewed by Keith Miller.

ENABLE_SAMPLING_PROFILER does not depend on ENABLE_JIT now since it can be
used with LLInt ASM interpreter.

  • Source/cmake/WebKitFeatures.cmake:

Source/JavaScriptCore:

LLInt ASM interpreter is 2x and 15% faster than CLoop interpreter on
Linux and macOS respectively. We would like to enable it for non JIT
configurations in X86_64 and ARM64.

This patch enables LLInt for non JIT builds in X86_64 and ARM64 architectures.
Previously, we switch LLInt ASM interpreter and CLoop by using ENABLE(JIT)
configuration. But it is wrong in the new scenario since we have a build
configuration that uses LLInt ASM interpreter and JIT is disabled. We introduce
ENABLE(C_LOOP) option, which represents that we use CLoop. And we replace
ENABLE(JIT) with ENABLE(C_LOOP) if the previous ENABLE(JIT) is essentially just
related to LLInt ASM interpreter and not related to JIT.

We also replace some ENABLE(JIT) configurations with ENABLE(ASSEMBLER).
ENABLE(ASSEMBLER) is now enabled even if we disable JIT since MacroAssembler
has machine register information that is used in LLInt ASM interpreter.

Source/WTF:

This patch adds ENABLE(C_LOOP) which indicates we use CLoop as the interpreter.
Previously, we used !ENABLE(JIT) for this configuration. But now, we have
a build configuration that has LLInt ASM interpreter (not CLoop) and !ENABLE(JIT).

We enable LLInt ASM interpreter for non JIT environment in X86_64 and ARM64 architectures.
And we enable ENABLE(ASSEMBLER) for non JIT environment since it offers machine register
information which is used for LLInt and SamplingProfiler.
