This is the next step to test the GC better: We zap the code region of {WasmCode} objects which are detected to be unused. This is tested in the future variant, so ClusterFuzz has a chance to catch missing references.

The WebAssembly JavaScript Interface specifies[1] that exported functions are not constructors, hence do not have the "prototype" property. This is not true for asm.js exported functions which are expected to look like normal functions (or constructors).

This CL implements the first set of diagnostic notifications. When Torque compilation fails, the language server translates the Torque error into a diagnostics notification and pushes it to the client. Note that per specification, the server is responsible to manage the state of all published diagnostics. This means that the server is also responsible for clearing out previous notifications if they become stale.

We had one use of OS_CHROMEOS in mksnapshot. OS_CHROMEOS is defined if gn's `is_chromeos` is true, which checks `current_os`. `current_os != target_os` can happen if we're building with a non-default toolchain, which happens often on CrOS, since `mksnapshot` is a host binary. Tested by manually verifying that .text.hot.embedded now shows up on arm32/aarch64 builds of embedded.S.

There seems to be an issue where LTO inlines the icache flushing method but removes the save and restore of the r7 register which is clobbered for the icache flush syscall.

Block binary coverage currently also relies on invocation counts on the feedback vector, which are not maintained in optimized code. This fixes the SFI::IsInlineable predicate to also prevent inlining functions when 1. binary coverage is enabled and 2. the function has no reported binary coverage.

We translate stores with TaggedXXX (XXX in {"", "Signed", "Pointer"}) representation in CSA into stores of CompressedXXX with a ChangeTaggedXXXToCompressedXXX in the raw-machine-assembler. This way, CSA doesn't need to know about Compressed values since we are introducing an explicit "compress" node. Also, on ARM64, removed CheckPageFlagSet and CheckPageFlagClear since CheckPageFlag can be used for both cases. Moved CheckPageFlag to the TurboAssembler (from MacroAssembler) since it was needed on code-generator-arm64.cc.
