all: format code according to Go 1.19 rules
...
Go 1.19 started reformatting code in a way that makes it more obvious
how it will be rendered on pkg.go.dev. It gets it almost right, but not
entirely. Therefore, I had to modify some of the comments so that they
are formatted correctly.

riscv: use MSTATUS.MIE bit instead of MIE to disable interrupts
...
This should behave the same but is compatible with the ESP32-C3 which
lacks the MIE CSR (but does have the MSTATUS CSR).

compiler: add support for atomic operations

all: replace ReadRegister with AsmFull inline assembly
...
This makes AsmFull more powerful (by supporting return values) and
avoids a compiler builtin.
