The runtime test whether the compiler supports arithmetic shift of
negative signed numbers currently relies on undefined behavior in C,
which means that all bets are off regarding whether the condition
that follows passes or fails, regardless of whether the compiler in
fact supports arithmetic shift or not.
Relevant quote from ISO C99 (6.5.7/4)
The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits
are filled with zeros. If E1 has an unsigned type, the value of the result
is E1 × 2^E2, reduced modulo one more than the maximum value representable
in the result type. If E1 has a signed type and nonnegative value, and
E1 × 2^E2 is representable in the result type, then that is the resulting
value; otherwise, the behavior is undefined.
For historic purposes, let's keep the test in place (although it is doubtful
we actually need it) but rewrite it in a way that prevents compilers from
this century from doing whacky things with it.

The EBC instruction set supports memory and MMIO access, but not
I/O port access. Add EBC support to BaseIoLibIntrinsic that
generates an ASSERT() if the IoReadXX()/IoWriteXX() APIs are used.
This matches the implementation for other CPU types that do not
support I/O port access.

They support both blocking and non-blocking SCSI Read/Write operation
depending on the optional parameter 'Event' passed to those APIs.
When 'Event' is NULL, these four functions will call the non-EX version
couterparts to execute blocking SCSI I/O. When 'Event' is not NULL,
non-blocking I/O operation is executed.

Note that using FixupData is somewhat pointless for relocations targeting
instructions rather than data items, since the program cannot typically
modify its own instructions, and the second pass should be performed
unconditionally. But let's just fix it for now.
