Version check for polyfills

[SemenchenkoVitaliy]

Sometimes we need to implement polyfills for older Node.js versions and for this we have to check version manually like:

const vArr = process.versions.node.split('.').map(num => parseInt(num));
if (vArr[0] > 8 || (vArr[0] === 8 && vArr[1] >= 2)) {
  ...
}

I propose to implement function that will check if process' version is older than required.

if (common.nodeVersionCompatible('8.2')) {
  ...
}

or

if (common.v8VersionCompatible('8.2')) {
  ...
}

WDYT?

AFAIK we need to check that the current version is equal or higher than the specified version, not compatible.
Example: we only use mkdip polyfill for <10.12.0.

Version	Polyfill	v10.12.0 compatible
8.0.0	✔️	❎
10.0.0	✔️	❎
10.12.0	❎	✔️
11.0.0	❎	❎

@nechaido Agree, function name should be changed. What about verifyVersion or checkVersion? Can as well make compareVersions.
