    cppgc: shared-cage: Remove heap-specific metadata from cage-header · 62159ea3
    Anton Bikineev authored
    The CL is a prerequisite for the shared cage. Instead of storing
    state variables (is_incremental_marking_in_progress,
    is_young_generation_enabled) in the cage metadata, the CL moves them to
    HeapHandle. The HeapHandle pointer is now retrieved from page-headers.
    
    To make sure that the write-barrier code is better optimized, the
    HeapHandle definition is moved to internal/ headers. The part of
    BasePage that contains HeapBase (i.e. HeapHandle) pointer is also
    extracted and moved to the headers.
