Tyler Mandry ba6e2b3a31 Rollup merge of #76500 - richkadel:mir-graphviz-dark, r=tmandry ... Add -Zgraphviz_dark_mode and monospace font fix Many developers use a dark theme with editors and IDEs, but this typically doesn't extend to graphviz output. When I bring up a MIR graphviz document, the white background is strikingly bright. This new option changes the colors used for graphviz output to work better in dark-themed UIs. <img width="1305" alt="Screen Shot 2020-09-09 at 3 00 31 PM" src="https://user-images.githubusercontent.com/3827298/92659478-4b9bff00-f2ad-11ea-8894-b40d3a873cb9.png"> Also fixed the monospace font for common graphviz renders (e.g., VS Code extensions), as described in https://github.com/rust-lang/rust/pull/76500#issuecomment-689837948 **Before:** <img width="943" alt="Screen Shot 2020-09-09 at 2 48 44 PM" src="https://user-images.githubusercontent.com/3827298/92658939-47231680-f2ac-11ea-97ac-96727e4dd622.png"> **Now with fix:** <img width="943" alt="Screen Shot 2020-09-09 at 2 49 02 PM" src="https://user-images.githubusercontent.com/3827298/92658959-51451500-f2ac-11ea-9aae-de982d466d6a.png">		2020-09-09 21:02:35 -07:00
