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).

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.

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.

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.

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.

src/runtime: improve float/complex hashing

This allows positive and negative zero to hash to the same value,

This is not perfect, but the best I could do without
