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.

Sam Clegg 65d6380cd6 [WebAssembly] Allow signautre of entry function to be flexible
Since we a no longer using this function for the wasm start
section we don't actually care what its signature is.

Sam Clegg 752494bfe3 [WebAssembly] Check function signatures by default
But only produce a warning (for now) unless --fatal-warnings
is passed.

Rui Ueyama f05124e60c Use wasm-ld instead of "lld -flavor wasm".
Invoking lld as ld.lld, ld.ld64, lld-link or wasm-ld is preferred
than invoking lld as lld and pass an -flavor option. We have "lld"
file mostly for historical reasons.

Sam Clegg 70683b2f75 [WebAssembly] Use inline target tripple in test cases
This is somewhat preferable since (in many cases) it allows llc
to be run directly on the .ll files without having to pass the
`-mtriple` argument.

Sam Clegg 77ee17d191 [WebAssembly] Remove custom handling for undefined entry
This code was needed back when we were not able to write
out the synthetic symbol for main.

Add tests to make sure we can handle this now.

Sam Clegg 2e25e896fb [WebAssembly] Improve wasm test cases
Add test for weakly defined symbols with the same name

Improve test for call-indirect to include the same call in two
different objects. This lays the ground work to improve the
output via de-duplicating the indirect call table:

Also make all tests consistently pass -mtriple rather than
declaring in the sources.

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.
