Gas profiler does not give a name to getter functions for public variables

[benber86]

When accessing a public variable and generating a gas profile, the profiler returns unnamed instead of the getter function's name

Example: https://try.vyperlang.org/hub/user-redirect/lab/tree/Gas%20Profile%20Public%20Variable.ipynb

import boa
from boa.profiling import get_call_profile_table, get_line_profile_table
from boa.vm.gas_meters import ProfilingGasMeter

seeder = boa.env.generate_address()
trader = boa.env.generate_address()
coin_a = boa.load("ERC20.vy", "coinA", "cA", 18)
coin_a._mint_for_testing(seeder, 1000000000000000000000000)

with boa.env.gas_meter_class(ProfilingGasMeter):
    with boa.env.prank(seeder):
        coin_a.transfer(trader, 100000000000000000000)
        coin_a.balanceOf(trader)

get_call_profile_table(boa.env)

I would expect to see balanceOf in the profiler, but instead it's listed as unnamed. (I would also expect the gas stats to actually appear in the table, even though it may not be the orthodox usage of the feature).

the gas stats not appearing is a drawback of the table renderer, they just get lost if there is truncation. we should also export the gas results to csv or a prof file honestly.

[charles-cooper]

btw, i think public variables not appearing is a bug in vyper's source map generation, which should have been fixed in 0.4.0 (https://github.com/vyperlang/vyper/commit/a91af13db9d6d89e6c2139c1b28c490845f06e13 if i'm not mistaken). can you try the beta and see if there are still issues?

@benber86 can we close this?
