      Revert "[cleanup] Refactor the Factory" · 503e07c3
      Michael Achenbach authored 
      This reverts commit f9a2e24b.

Reason for revert: gc stress failures not all fixed by follow up.

      [cleanup] Refactor the Factory · f9a2e24b
      Jakob Kummerow authored 
      There is no good reason to have the meat of most objects' initialization
logic in heap.cc, all wrapped by the CALL_HEAP_FUNCTION macro. Instead,
this CL changes the protocol between Heap and Factory to be AllocateRaw,
and all object initialization work after (possibly retried) successful
raw allocation happens in the Factory.

This saves about 20KB of binary size on x64.

      [bigint] Encapsulate internals in MutableBigInt · 977da550
      Jakob Kummerow authored 
      This CL creates the invariant that the BigInt class treats
BigInt objects as immutable. Writing to new BigInt objects
as part of their construction is done by the MutableBigInt
helper class, which in turn is hidden as an implementation
detail in bigint.cc.
As a side effect, this refactoring enforces right-trimming
checks for all newly created BigInts, and ensures that all
BigInt allocations possibly exceeding kMaxLength check for
this case and throw a RangeError instead of crashing.
