1d9fb2ee61 [clang][Interp] Disable CFStringMakeConstantString test on AIX 
It's not only the fist CFSTR call that's broken on AIX.

0a739eb75f [clang][Interp] Implement __builtin___{CF,NS}StringMakeConstantString 
By doing the same thing the current interpreter does: Just passing on
the first parameter.

[clang][Interp] Implement __builtin_bitreverse (#71687) 
Since the return value of this function is slightly more involved than
the void/bool/int/size_t return values we've seen so far, also refactor
this.

[clang] Additional FP classification functions (#69041) 
C language standard defined library functions `iszero`, `issignaling`
and `issubnormal`, which did not have counterparts among clang builtin
functions. This change adds new functions:

    __builtin_iszero
    __builtin_issubnormal
    __builtin_issignaling

They provide builtin implementation for the missing standard functions.

673ef8ceae Re-land "[clang][Interp] Make sure we push integers of the correct size" 
This also re-reverts the commit implementing __builtin_strlen.

I was unable to reproduce the msan issue with an msan-enabled build (for
infrastructure reasons), but I think fixing the target-dependent int
sizes in the implementation of __builtin_fpclassify should work.
