0928882df3 [WebAssembly] Use a separate wasm data segment for each global symbol
This is stepping stone towards honoring -fdata-sections
and letting the assembler decide how many wasm data
segments to create.

9f8cb471ac [WebAssembly] Only treat imports/exports as symbols when reading relocatable object files
This change only treats imported and exports functions and globals
as symbol table entries the object has a "linking" section (i.e. it is
relocatable object file).

In this case all globals must be of type I32 and initialized with
i32.const.  This was previously being assumed but not checked for and
was causing a failure on big endian machines due to using the wrong
value of then union.

3ba6566741 [WebAssembly] Be consistent in generating trivial test input files
For each checked-in wasm file, make sure the there is
corresponding .ll file that can be used to regenerate it
if needed.

Add test/Object/Inputs/trivial-object-test.wasm to match other
formats and add some new wasm tests in test/Object.
