In the earlier implementation of GenerateDoubleToObject the context
is loaded from the parent's frame. rsi is clobbered because it is used
to store kHoleNan constnat. It is not always safe to peek at
the parents frame. Bytecode handlers have TypedFrame and the type of
frame is stored at FP + 1. GenerateDoubleToObject expects context
to be store at that place. In the current implementation rsi is pushed
onto the stack and is popped when exiting this function.

Previously all code stubs (i.e. both platform and Crankshaft code stubs)
preserved the context register for full-codegen (neither Ignition, nor
TurboFan nor Crankshaft require this or would benefit from this), but
the newly introduced TurboFanCodeStubs no longer do this and there's no
need to, so we have to make sure in full-codegen that we restore the
context register after intrinsic calls, which potentially call
TurboFanCodeStubs.

Drive-by-fix: VisitThisFunction can be made platform independent.

Test case objects were sorted without key function, resulting
in random sort order. On sharded builds, the shards are
determined by the sort order and rely on a deterministic
sorting. This led to random cctest and unittest cases being
dropped or executed twice on sharded testers.

for mips64r6. Macroassembler Jump and Call functions now use JIC and
JIALC if branch delay slot is not used. Code patching is adjusted to

Other changes where mips32r6 uses jr/jalr are not done because mips64r6

Migrate Math.ceil, Math.round and Math.trunc to TurboFan code stubs,
similar to what we did with Math.floor, and make these builtins properly
optimizable in TurboFan via appropriate simplified operators NumberCeil,
NumberRound and NumberTrunc, which are intended to be reusable for
ToInteger and ToLength optimizations that will be done in a followup CL.

Also allows us to kill the funky %RoundNumber runtime function, which
was quite heavy.

Improve test coverage for Math.ceil and Math.trunc a lot, especially
making sure that we also properly trigger the TurboFan builtin reducer
case.
