Nicholas Wilson 5639da89a9 [WebAssembly] Reorder synthetic functions to come first
This matches the existing ordering that's been there for globals
for a while (__stack_pointer coming first).

Sam Clegg 99eb42c0c5 [WebAssembly] Remove DataSize from linking metadata
This means we don't need to write the linking metadata section
at all for executable (non-relocatable) output.

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 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:
   https://reviews.llvm.org/D40989

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.
