If the flag '-m64' is used on a 32-bit architecture/machine having
int32_t set to 'long', then these int32_t are forced to 64-bit ...
So, ignore the effect of -m64 on these archs and ignore
'64-bit only' tests on them.

Casts to integer used to be done with only 2 instructions:
OP_CAST & OP_SCAST.
Those are not very convenient as they don't reflect the real
operations that need to be done.
This patch specialize these instructions in:
- OP_TRUNC, for casts to a smaller type
- OP_ZEXT, for casts that need a zero extension
- OP_SEXT, for casts that need a sign extension
- Integer-to-integer casts of the same size are considered as
a NOPs and are, in fact, never emitted.

Currently all casts to pointers are processed alike. This is
simple but rather unconvenient in later phases as this
correspond to different operations that obeys to different
rules and which later need extra checks.
Change this by using a specific instructions (OP_UTPTR) for
[unsigned] integer to pointers.

Currently, casts from floats to integers are processed like
integers (or any other type) to integers. This is simple but
rather unconvenient as it correspond to different operations
that obeys to different rules and which later need extra checks.
Change this by directly using specific instructions:
- FCVTU for floats to unsigned integers
- FCVTS for floats to signed integers

* merge the tests about implicit & explicit casts in a
single file as there was a lot of redundancy.
* shuffle the tests to linear/ or optim/
