c096f35224 runtime: handle negative sleep times 
This change fixes the edge case where a negative sleep time is provided.
When this happens, the call now returns immediately (as specified by the docs for time.Sleep).

d30f8b6ed6 os.Stat: returned error on nonexistent path did not satisfy IsNotExist 
Add direct test for the problem to make the fix commit clearer.

Noticed while implementing MkdirTemp on mac; the upstream tests for MkdirTemp fail without this.

0f69d016a0 Added realloc implementation to GCs 
When using the latest wasi-libc I experienced a
panic on an attempt to call realloc. My first attempt to
add it to arch_tinygowasm.go was obviously not good (PR #2194). So here
is another suggestion.

ef8c1a187d transform: allocate the correct amount of bytes in an alloca 
When I wrote the code originally, I didn't know about SetAlignment so I
hacked a way around it by allocating [...]uintptr types. However, this
allocates a few too many bytes in some cases.
This commit changes this to only allocate the space that we actually
need.

The code size effect is mixed, but generally positive. The combined
average is reduced by 0.27% with more programs being reduced in size
than are increasing in size.

d6c892fe7b src/runtime: fix nil map dereference 
Operations on nil maps are accepted and shouldn't
panic. The base hashmapGet/hashmapDelete handled
nil-maps correctly, but the hashmapBinary versions
could segfault accessing the nil map while trying
to hash the key.

Fixes #2341

b13c993565 compiler: fix ranging over maps with particular map types 
Some map keys are hard to compare, such as floats. They are stored as if
the map keys are of interface type instead of the key type itself. This
makes working with them in the runtime package easier: they are compared
as regular interfaces.

Iterating over maps didn't care about this special case though. It just
returns the key, value pair as it is stored in the map. This is buggy,
and this commit fixes this bug.

1903cf23c9 src/runtime: improve float/complex hashing 
This allows positive and negative zero to hash to the same value,
as required by Go.

This is not perfect, but the best I could do without
revamping all the hash funtions to take a seed.

Fixes #2356
