Fix counting of the local variables
...
The code assumed that the number of `Local` and number of locals is the
same thing. In reality though it is not. `Local` actually represents a
group of locals with the same type. The group can declare more than one
variable and the number of them is returned by `Local::count`.
In this PR we acknowledge this fact. Along the way we add a checked
arithmetic for locals_count and max_stack_height summation.

Otherwise every crate that depends on this needs to also
directly depend on parity_wasm.

Don't generate duplicate thunks
...
Previously, functions that appear in multiple places
(exported, start function, table) would generate a thunk
for each place they appear in. Those additional thunks are
identical and only only one of them would be referenced.
Main offender are tables with redundant entries.
This commit eliminates those duplicate thunks without adding
any additional overhead.

Fix Instruction::CallIndirect stack height metering
...
The stack height metering for functions containing
CallIndirect was wrong. The code did not take into
consideration that is pops one value from the stack.
The effect was that the stack height of functions
using this instruction was higher than its real height.

Preserve "deploy" when optimizing pwasm ctor module
...
When optimizing the constructor module for a PWasm contract the "deploy" symbol is preserved instead of the "call"
symbol. Before this change `build` would error for PWasm contracts because `pack_instance` would not find the "deploy"
symbol in the optimized contract.
