Hm, the test failure is a latent bug in picolibc, and updating to 1.8.12 actually exposed it in newer code I guess I'll have to send them a PR or something |

This is a prereq for enabling
setjmp-based panic/recover handling on xtensa; only 1.8.7+ have the right bits to be able to do spilling without an OS (older versions do asyscallwhich of course fails in tinygo).Basically everything in this PR is the
newlibandtinystdiopromotions.As a result, some more tests start working due to better math stuff, which I've enabled. The only trick there is that the intrinsics for sin/cos need to point to the right places.
I tested everything I could locally, but we'll see if CI is mad.
