Ross McIlroy 2f5d90a816 [d8] Add a stress-background-compile mode
Adds a stress-background-compile mode which runs compilation on a background
thread at the same time as compiling on the main thread to flush out races.
This is added as one of the variants, removing stress_asm_validation since this
is no longer a useful variant.
