[PATCH olang 0/5] extend unsined integers types (u8, u16, u64)

[Carlos Maniero <carlos@maniero.me>]

The olang was supporting only u32 yet there was an inconsistency because
we were always using 8 bytes to store information on stack when u32
actually requires only 4 bytes. We were also using rax for these
operations when 32bits operation should use eax.

This patch enables all unsigned types and use the proper
instruction/register.

Carlos Maniero (5):
  parser: replace type enum to an struction string id representation
  checker: scope: populate symbol's type
  codegen: fix map simbol list type
  codegen: calculate the variable offset based on symbol type
  codegen: perform mov instructions based on variable type
