Rather than using a separate hash table for doubles, use the same
biases hash approach we use for everything else. Either way works
fine, but there doesn't seem to be any strong reason to use a
different approach for doubles than we use for other cases.
Rather than keeping track of a separate valid_T set (which must
always be in sync with map_T), use a dummy value in map_T to
denote unallocated temporaries.
If the result has no uses we need to allocate it when visiting the
defining instruction. However, we should still go through the
logic to remove the temporary from the taken map afterwards,
as the temporary can still be reused prior to the defining
instruction.
This seems to be a leftover from when we were storing cache slots
inside literals and had to prevent merging of literals with
incompatible cache slots. Nowadays the LITERAL_* classification
is not actually used for anything, we're only interested in the
number of related literals.
Nowadays we include the content of all the related literals in the
cache key, so DECLARE_CLASS (where both literals cannot be derived
from each other) no longer needs this special case.
This allows users to use PECL/zip, which is well maintained and often
brings new features which are not yet available in ext/zip, as drop-in
replacement for the official Windows php-src builds.
Closes GH-8549.
Extensions may (and do) write to stderr in mshutdown and similar. In
the best case, with the stderr stream closed, it's just swallowed.
However, some libraries will do things like try to detect color, and
these will outright fail and cause an error path to be taken.
