Dominic Chen 4a9b99ee92 [WebAssembly] Re-enable disabled debug value test 
Summary:
This test was resulting in asan/valgrind failures due to undefined
DWARF register mappings for WebAssembly, and was disabled in r278495.
These have been resolved.

Dominic Chen 6ba19659cb Improve virtual register handling when computing debug information 
Summary: Some backends, like WebAssembly, use virtual registers instead of physical registers. This crashes the DbgValueHistoryCalculator pass, which assumes that all registers are physical. Instead, skip virtual registers when iterating aliases, and assume that they are clobbered.
