These macros produced a lot of errors with ubsan preventing us from
expanding the ubsan coverage on CIs.
C++ spec has such clause:
"If the prvalue of type "pointer to cv1 B" points to a B that is
actually a subobject of an object of type D, the resulting pointer
points to the enclosing object of type D. Otherwise, the result
of the cast is undefined."
Ubsan error example:
../src/compiler/glsl/builtin_functions.cpp:4945:4: runtime error: downcast of address 0x559b926abb50 which does not point to an object of type 'ir_instruction'

The "__inst" will contain the name used for the variable of type
"__type *". Parenthesis is not necessary as the name itself shouldn't
be an expression.

Through the glsl headers we had an odd mix of guards be that
"ifndef", "pragma once" neither or both.
Simplify things by using the more common ones (ifndef) and annotating
all the sources, barring the generated builting header -
builtin_int64.h.
The final header - udivmod64.h - is [seemingly] unused and on its way
out (patch purge it is on the mailing list).

No change in behavior. ralloc_size is equivalent to rzalloc_size.
That will change though.
Calls not switched to rzalloc_size:
- ralloc_vasprintf
- glsl_type::name allocation (it's filled with snprintf)
- C++ classes where valgrind didn't show uninitialized values
I switched most of non-glsl stuff to rzalloc without checking whether
it's really needed.

I do appreciate the cleverness, but unfortunately it prevents a lot more
cleverness in the form of additional compiler optimizations brought on
by -fstrict-aliasing.
No difference in OglBatch7 (n=20).
