Richard Musiol c0d82bb0ec all: rename WebAssembly instructions according to spec changes
The names of some instructions have been updated in the WebAssembly
specification to be more consistent, see
994591e51c.
This change to the spec is possible because it is still in a draft
state.

Go's support for WebAssembly is still experimental and thus excempt from
the compatibility promise. Being consistent with the spec should
warrant this breaking change to the assembly instruction names.

Austin Clements 4f3604d3f2 runtime, reflect: access runtime.reflectcall directly
Currently, package runtime contains the definition of reflect.call,
even though it's just a jump to runtime.reflectcall. This "push"
symbol is confusing, since it's not clear where the definition of
reflect.call comes from when you're in the reflect package.

Replace this with a "pull" symbol: the runtime now defines only
runtime.reflectcall and package reflect uses a go:linkname to access
this symbol directly. This makes it clear where reflect.call is coming
from without any spooky action at a distance and eliminates all of the
definitions of reflect.call in the runtime.

Richard Musiol c12399fffb all: enable vet/all for js/wasm and fix vet issues
This commit enables vet/all for the js/wasm architecture. It got
skipped initially because the codebase did not fully compile yet
for js/wasm, which made vet/all fail.

startTimer and stopTimer are not needed in the syscall package.
Removed their assembly code since their Go stubs were already gone.

Richard Musiol 35ea62468b runtime: add js/wasm architecture
This commit adds the js/wasm architecture to the runtime package.
Currently WebAssembly has no support for threads yet, see
https://github.com/WebAssembly/design/issues/1073. Because of that,
there is no preemption of goroutines and no sysmon goroutine.
