Nikita SmithandRyan Fleury d3dedd8bef simplifying symbol table scopes 
Linker cannot register extern import symbols initially because
the import object files are not available until all other object files are
resolved. To work around this, we create a stub weak symbol and assign
it to each import symbol. This allows linker to proceed. Once the import
object files are generated, linker replaces the stub symbol with
the actual ones from the import objects.

Nikita Smith 4a2e1dd8d0 switch to thread safe hash trie map 
Initial implementation of the symbol table allowed us to push symbols
from one thread at a time and required a wonky lock-step and spread out
logic for replacing symbols. And because it was a externally chained
hash table we had to guesstimate optimal capacity for small and big targets.
We erred on the side of larger capacity to prevent degradation and
rehashing, however this meant small targets had to spent unreasonable
amount of time memory allocing slots. With hash trie we can dynamically
scale up to 4 ^ 32 items and atomically replace symbols when needed. Neat!
