fix JSCore segmentation fault on 64-bit big endian systems

In CodeBlock.cpp the code preparing the operands of op_get_from_scope writes
the property offset as pointer size (hence 64 bit) value:

2141: instructions[i + 6].u.pointer = reinterpret_cast<void*>(op.operand);

while the same slot is accessed later by the jitted code as 32 bit integer:

macro getProperty(slow)
   loadisFromInstruction(6, t1)

This fails on big endian targets since the integer access takes the higher
part of the 64 bit value.

let Bison generate the header directly

Forwarded: https://github.com/qtwebkit/qtwebkit/pull/1012
Last-Update: 2020-08-04

Starting with Bison 3.7, the generated C++ file #include's the header
by default, instead of duplicating it. So we should not delete it.

Remove the code to add #ifdef guards to the header, since Bison adds
them itself since version 2.6.3.

Last-Update: 2017-11-20

The code unconditionally uses PATH_MAX, which is POSIX-optional.

This fixes the build on platforms without it, such as GNU/Hurd.
