Sam Clegg fc1a912b9b [WebAssembly] De-dup indirect function table.
Create the indirect function table based on symbols rather
than just duplicating the input entries.  This has the
effect of de-duplicating the table.

This is a followup to the equivalent change made for globals:

Partially based on a patch by Nicholas Wilson:

Sam Clegg 74fe0ba105 [WebAssembly] Fix symbol exports under -r/--relocatable
This change cleans up the way wasm exports and globals
are generated, particualrly for -r/--relocatable where
globals need to be created and exported in order for
output relocations which reference them.

Remove the need for a per file GlobalIndexOffset and
instead set the output index for each symbol directly.
This simplifies the code in several places.

Rui Ueyama bdc5150984 Always evaluate the second argument for CHECK() lazily.
This patch is to rename check CHECK and make it a C macro, so that
we can evaluate the second argument lazily.

Sam Clegg a681a1167e [WebAssembly] Remove wasm/Strings.cpp+h
This file contained only a single function that was only
really needed in one place, so just inline it.

Sam Clegg c94d393ad5 [WebAssembly] Initial wasm linker implementation
This linker backend is still a work in progress but is
enough to link simple programs including linking against
library archives.
