When we pass function arguments on the stack, untagged parameters
"come first", i.e. are put to lower addresses / can be popped off

parameters (belonging to its caller's frame), it must skip past
any untagged parameters at the top of the caller's frame.

WireBytesStorage is the class used to access the wire bytes of a
function for compilation. It is stored and passed in a shared_ptr,
because it can be updated while compilation is running, and the
compilation threads will keep the old reference alive until the last
reference is dropped.
This CL fixes a few issues where we unnecessarily passed a reference
to the shared_ptr instead of just a raw pointer, and changes one
copy-assign into a move-assign to avoid an unneeded reference increase
and decrease.

This removes/replaces header includes with the aim of shrinking the
size of the inline header cycle. Specifically before this CL, there was
a single Strongly-Connected Component comprising 60 header files from
src/objects and src/heap.
Now there are two 2 SCCs. The src/heap SCC has 6 files and depends on
the src/objects SCC, which has 50 files. Additionally some previously
implicit dependencies have been added.
Dependencies calculated using:
git grep "#include \"" *.h *.cc | sed 's/:#include "/ /;s/".*$//' | \
awk 'BEGIN {print "digraph deps {" } END {print "}"} {print "\""$1"\" -> \""$2"\""}'
SCCs found using sccmap from graphviz.
Also removes unused Cell::FromValueAddress method.
