[lld][WebAssembly] Convert some lld tests to assembly When we originally wrote these tests we didn't have a stable and fleshed out assembly format. Now we do so we should prefer that over llvm ir for lld tests to avoid including more part of llvm than necessary in order to run the test. This change converts just 30 out of about 130 test files. More to come when I have some more time. Differential Revision: https://reviews.llvm.org/D80361

[lld] Allow args::getInterger to parse args larger than 2^31-1 Differential Revision: https://reviews.llvm.org/D62933 llvm-svn: 362770

; Verify we can parse large integers such as when we ask for 2G of total
; memory.
[lld][WebAssembly] Handle 4gb max memories Summary: A previous change (53211a) had updated the argument parsing to handle large max memories, but 4294967296 would still wrap to zero after the options were parsed. This change updates the configuration to use a 64-bit integer to store the max memory to avoid that overflow.
