[dev.simd] cmd/compile: don't treat devel compiler as a released compiler

The compiler has a logic to print different messages on internal
compiler error depending on whether this is a released version of
Go. It hides the panic stack trace if it is a released version. It
does this by checking the version and see if it has a "go" prefix.
This includes all the released versions. However, for a non-
released build, if there is no explicit version set, cmd/dist now
sets the toolchain version as go1.X-devel_XXX, which makes it be
treated as a released compiler, and causes the stack trace to be
hidden. Change the logic to not match a devel compiler as a
released compiler.
