Subject: [WebAssembly] Rename --lto-no-new-pass-manager to --no-lto-new-pass-manager
X-Git-Tag: llvmorg-13-init~4659
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=31e03a9bd9561e6b21e4e1f5b80a8316de624876;p=platform%2Fupstream%2Fllvm.git

[WebAssembly] Rename --lto-no-new-pass-manager to --no-lto-new-pass-manager

In addition, disallow `-lto-new-pass-manager` (see D79371).

Note: the ELF port has also adopted --no-lto-new-pass-manager
