cmd/compile: introduce special ssa Aux type for calls This is prerequisite to moving call expansion later into SSA, and probably a good idea anyway. Passes tests. This is the first minimal CL that does a 1-for-1 substitution of *ssa.AuxCall for *obj.LSym. Next step (next CL) is to make this change for all calls so that additional information can be stored in AuxCall.

cmd/compile: fold offset into address on Wasm On Wasm, the offset was not folded into LoweredAddr, so it was not rematerializeable. This led to the address-taken operation in some cases generated too early, before the local variable becoming live. The liveness code thinks the variable live when the address is taken, then backs it up to live at function entry, then complains about it, because nothing other than arguments should be live on entry. This CL folds the offset into the address operation, so it is rematerializeable and so generated right before use, after the variable actually becomes live. It might be possible to relax the liveness code not to think a variable live when its address being taken, but until the address actually being used. But it would be quite complicated. As we're late in Go 1.11 freeze, it would be better not to do it. Also, I think the address operation is rematerializeable now on all architectures, so this is probably less necessary. This may also be a slight optimization, as the address+offset is now rematerializeable, which can be generated on the Wasm stack, without using any "registers" which are emulated by local variables on Wasm. I don't know how to do benchmarks on Wasm. At least, cmd/go binary size shrinks 9K. Fixes #25966.

cmd/compile: add 32 bit float registers/variables on wasm Before this change, wasm only used float variables with a size of 64 bit and applied rounding to 32 bit precision where necessary. This change adds proper 32 bit float variables. Reduces the size of pkg/js_wasm by 254 bytes.
