Chris Tate bc6359443a Divide mid-size executables into at least eight partitions ...

An executable's LLVM text was divided into one partition per 4 MiB, so a
program under 4 MiB was optimized and compiled on one thread, and one of
up to 32 MiB used fewer than eight cores. A module over 1 MiB now gets at
least eight partitions of 512 KiB or more: four up to 2 MiB, and eight up
to 32 MiB. Larger modules keep one partition per 4 MiB. The count still
depends only on the module's size.
