Is this up-front 'contractor waives all lien rights' clause good in Illinois?

No. Under 770 ILCS 60/1(d) an agreement to waive any right to enforce or claim any lien under the Mechanics Lien Act, or an agreement to subordinate the lien, where the agreement is in anticipation of and in consideration for the awarding of a contract or subcontract, express or implied, to perform work or supply materials for an improvement upon real property, is against public policy and unenforceable. The Act states the mirror rule too: where a contract provision's legal effect is that no lien may be filed or the lien is subordinated, and the provision "is not prohibited by this Act, such provision shall be binding if made as part of an agreement not prohibited by this Act" (770 ILCS 60/21(b)), so a waiver or subordination given outside § 1(d)'s in-anticipation-of-award setting holds. A pay-if-paid or pay-when-paid term is no defence to a subcontractor's or supplier's lien claim (§ 21(e)). And where a filed claim for lien is paid with the cost of filing, or suit to enforce it is not instituted after demand within the time the Act limits, the person who filed it must acknowledge satisfaction or release in writing on the written demand of the owner, lienor or any person interested in the real estate, and on neglect to do so for 10 days owes the owner $2,500 plus costs and reasonable attorney's fees (§ 35(a)).

The trap

The vice is the timing and the consideration, not the words: what § 1(d) reaches is an agreement "in anticipation of and in consideration for the awarding of a contract or subcontract", so the same sentence in the prime contract signed to WIN the work is, in the section's own words, against public policy and unenforceable, while a waiver or release given later for work already done is outside the words that void it. Read the carve-out for what it is, though. Section 1(d)'s own saving is narrower than a progress-payment waiver: it preserves "release of lien under subsection (b) of Section 35", and § 35(b) is the recording provision. A satisfaction or release may be filed with the recorder of deeds where the claim for lien was filed and once filed "shall forever thereafter discharge and release the claim for lien and shall bar all actions brought or to be brought thereupon", which is the back end of § 35(a)'s duty to acknowledge satisfaction of a FILED claim that has been paid. Nothing in § 1(d) names a progress-payment waiver. The subordination half catches the clause drafters use instead of a waiver (agreeing in advance that the lien sits behind the construction lender) with one exception in the statute: subordination to a mortgage securing a construction loan is permitted if agreed after more than 50% of the loan has been disbursed to fund improvements. Section 1(c) adds that taking additional security is not a waiver unless made one by express agreement and not prohibited by the Act.
