Allow to run TypeScript (Compiler, Services) in strict mode

[kpreisser]

TypeScript Version: master

Currently, tsc.js, typescriptServices.js and tsserver.js cannot be run in a strict mode environment due to using the identifier static in checker.ts.

static is a reserved identifier in strict mode, so if you run tsc.js with Node in strict mode, it will fail:

C:\Users\VPC\Desktop\TypeScriptOrg\built\local>node --use_strict tsc.js
C:\Users\VPC\Desktop\TypeScriptOrg\built\local\tsc.js:24019
                    var static = ts.forEach(member.modifiers, function (m) { return m.kind === 113; });
                        ^^^^^^
SyntaxError: Unexpected strict mode reserved word

I think it is reasonable to allow TypeScript to be run in a strict mode environment, by changing the name of the variable.

PS: Is there a reason why the TypeScript sources don't use strict mode in general?
Thanks!

I also encounter this when trying to compress typescript services using Closure compiler.

@mhegazy can I submit a pull request for this? Or you prefer to do it yourself?
