compiler: special slice bounds check for 64-bit numbers
...
It is allowed to index with an int64 even on a 32-bit platform, so we
have to handle that case. But make sure the normal case isn't penalized
by using 32-bit numbers when possible.

runtime: fix hashmap lookup of entries at position > 8
...
Bigger hashmaps (size > 8) use multiple buckets in a chain. The lookup
code looked at multiple buckets for a lookup, but kept checking the
first bucket for key equality.

Let each target handle its own initialization/finalization sequence

A few changes to make sure compiler-rt is correctly compiled (and
doesn't include host headers, for example).
This improves support for AVR, but it still doesn't work. Compiler-rt
itself doesn't really work for AVR either.

nrf: fix off-by-one in modulo of runtime.ticks
...
This code:
foo & 0xffffff
Is equivalent to this code:
foo % 0x1000000
However, to drop the high 8 bits, this calculation was used:
foo % 0xffffff
This is far more expensive (and incorrect), as it needs an actual modulo
operation which increases code size and probably reduces speed on a
Cortex-M4 and needs library functions for a Cortex-M0 increasing code
size by a much bigger amount.

This is one step towards removing unnecessary special casts in most

avr: convert initialization from asm to Go
...
This increases code size by 1 instruction (2 bytes) because LLVM isn't
yet smart enough to recognize that it doesn't need to clear a register
to use 0: it can just use r1 which is always 0 according to the
convention. It makes initialization a lot easier to read, however.
