Use zend_string_release_ex() instread of zend_string_release() in places, where we sure about string persistence.

Avoid useless checks, using zend_string_efree(), in cases where the string is known to be a temporary allocated zend_string.

Fix unused variable warnings

Avoid using _N in SSE code

The _N constant is already defined in OpenSSL. Instead use some
more explicit variable names.

Use const pointers at some appropriate places

slashchars are 16 bytes aligned

Optimized str_rot13 with SSE2 instructions

Improve similar_text(), reduce recursive call to php_similar_char()

If the longest common substring is the leftmost common substring, there
is no need to check the string prefixes for further common substrings,
since there are none.

Fix def signature to match declaration

Optimized php_stripslash with SSSE3 instr

Simplified the codes (the penalty of loading unaligned address is negligible)

change layout

Move map out of loop

Optimized strrev with SSSE3

since strrev is not wildly used, and SSSE3 is defined default by some
compiler, so won't try to do ifunc here.

change argument parsing

Optimized base64_encode/decode with SIMD instructions

Fixed cpu feature check in reslover functions

Fix some misspellings

Use bool instead of boolean in proto
