[WebAssembly] Convert the remaining unit tests to the new wasm-object-file target.

Browse Source 
To facilitate this, add a new hidden command-line option to disable
the explicit-locals pass. That causes llc to emit invalid code that doesn't
have all locals converted to get_local/set_local, however it simplifies
testwriting in many cases.

floating-point constants.
//===---------------------------------------------------------------------===//
The function @dynamic_alloca_redzone in test/CodeGen/WebAssembly/userstack.ll
ends up with a tee_local in its prolog which has an unused result, requiring
an extra drop:
get_global $push8=, 0
tee_local $push9=, 1, $pop8
drop $pop9
[...]
The prologue code initially thinks it needs an FP register, but later it
turns out to be unneeded, so one could either approach this by being more
clever about not inserting code for an FP in the first place, or optimizing
away the copy later.
