60d2e70c06 Zend: fix overflow handling bug in non-x86 fast_add_function() 
The 'result' argument of fast_add_function() may alias with either
of its operands (or both). Take care not to write to 'result' before
reading op1 and op2.

92d27ccb05 Constify streams API and a few other calls down the rabbit hole. 
(`char *` to `const char *` for parameters and few return values)
In a few places int len moved to size_t len.

5b121eb04d Fix #64780 (PHP 5.5 builds are broken with GCC 3) 
A recent change (by me) introduced a call to __builtin_offsetof()
into zend_operators.h which is not defined by GCC prior to
version 4.

Changed the code to use offsetof() instead: this is defined in
<stddef.h>, so #include this header conditionally (#ifdef GNUC)

a86fcfbc1d Fix rounding of zend_dval_to_lval 
Now rounding is always towards zero; the rounding can be though as if
occurring on the original double. Only relevant for the 32-bit long
variant.

77566edbaf Fix zend_dval_to_lval outside 64bit integers range 
PHP should preserve the least significant bits when casting from double
to long. Zend.m4 contains this:

AC_DEFINE([ZEND_DVAL_TO_LVAL_CAST_OK], 1, [Define if double cast to long preserves least significant bits])

If ZEND_DVAL_TO_LVAL_CAST_OK is not defined, zend_operators.h had an
inline implementation of zend_dval_to_lval() that would do a cast to an
int64_t (when sizeof(long) == 4), then a cast to unsigned long and
finally the cast to long.

While this works well for doubles inside the range of values of the type
used in the first cast (int64_t in the 32-bit version and unsigned long
in the 64-bit version), if outside the range, it is undefined behavior
that WILL give varying and not particularly useful results.

This commit uses fmod() to first put the double in a range that can
safely be cast to unsigned long and then casts this unsigned long to
long. This last cast is implementation defined, but it's very likely
that this gives the expected result (i.e. the internal 2's complement
representation is unchanged) on all platforms that PHP supports. In any
case, the previous implementationa already had this assumption.

This alternative code path is indeed significantly slower than simply
casting the double (almost an order of magnitude), but that should not
matter because casting doubles with a very high absolute value is a
rare event.

aa12cdc361 Improve x86 inline assembler 
- added cc annotation to inline asm that clobbers the condition
  flags
- remove hardcoded constants (IS_LONG,IS_DOUBLE)
- remove hardcoded offsets (zval->value, zval->type)
