8a91518633 Fix issues revealed by ECMAScript test262 
Cosmopolitan's QuickJS is now equally conformant and performant, with
the exception of Atomics, which have been disabled since Cosmopolitan
currently doesn't support pthreads.

a8945714e8 Make gdtoa less tunable (#104) 
The -fno-math-errno flag shouldn't impact libraries since it's mostly
intended for permitting the compiler to generate sqrt() instructions.

8da931a7f6 Add chibicc 
This program popped up on Hacker News recently. It's the only modern
compiler I've ever seen that doesn't have dependencies and is easily
modified. So I added all of the missing GNU extensions I like to use
which means it might be possible soon to build on non-Linux and have
third party not vendor gcc binaries.
