Scott Olson
20ced4a720
Replace const_to_ptr with const_to_value.
...
This reduces the number of allocations Miri makes drastically. The
`const_to_ptr` function was a lame hack that allocated for every since simple
constant, and all of those are avoided now, except for one extra allocation each
for string and bytestring literals which will be fixed in a followup commit.
There are a number of hacks such as `eval_operand_to_ptr` left over from this
commit, which will also be fixed in followup commits.

don't execute the first statement of a constant/static/promoted right away

This might create confusion, because attempting to execute a statement can cause
arbitrary stackframes to be added for the constants/statics/promoteds required by that
statement. Before this commit, the first statement of the last added stackframe was
executed immediately. Thus there was no way to inspect the state before that first
statement.
