Unlike many other bits in HCR_EL2, the description for this
bit does not contain the phrase "if ... this field behaves
as 0 for all purposes other than", so do not squash the bit

Instead, replicate the E2H+TGE test in the two places that

v8.1M brings four new insns to M-profile:
* CSEL : Rd = cond ? Rn : Rm
* CSINC : Rd = cond ? Rn : Rm+1
* CSINV : Rd = cond ? Rn : ~Rm
* CSNEG : Rd = cond ? Rn : -Rm
Implement these.

The t32 decode has a group which represents a set of insns
which overlap with B_cond_thumb because they have [25:23]=111

This group is currently defined using the {} overlap-OK syntax,

These will be useful for softfloat. I've included the extract/desposit
functions with the main Int128 header and not with cutils as we need
alternate versions for systems that don't have compiler support for
Uint128. Even with compiler support some stuff we need to
hand-hack (like clz128).

The -enable-fips option was added a long time ago to prevent the use of
single DES when VNC when FIPS mode is enabled. It should never have been
added, because apps are supposed to unconditionally honour FIPS mode
based on the '/proc/sys/crypto/fips_enabled' file contents.
