Paulo Matos 6d0c7bc17d [WebAssembly] Implementation of table.get/set for reftypes in LLVM IR 
This change implements new DAG nodes TABLE_GET/TABLE_SET, and lowering
methods for load and stores of reference types from IR arrays. These
global LLVM IR arrays represent tables at the Wasm level.

Sam Clegg 7d4ec5af6c [WebAssembly] Don't export __data_end and __heap_base by default. 
These can still be exported via --export if needed.

Sam Clegg 47e2b6b29e [WebAssembly] Don't error when --undefined symbols are not found 
This matches the behavior of the ELF linker where -u/--undefined
means symbols will get pulled in from archives but won't result
in link error if they are missing.

Also, don't actually great symbol table entries for the undefined
symbols, again matching more closely the ELF linker.

This also results in simplification of the code.
