UpdateTestChecks: Lanai triple support

UpdateTestChecks: Lanai triple support

Summary:
The assembly structure most resembles the SPARC pattern:
```
        .globl  f6                      ! -- Begin function f6
        .p2align        2
        .type   f6,@function
f6:                                     ! @f6
        .cfi_startproc
! %bb.0:
        st      %fp, [--%sp]
<...>
        ld      -8[%fp], %fp
.Lfunc_end0:
        .size   f6, .Lfunc_end0-f6
        .cfi_endproc
                                        ! -- End function
```
Test being affected by upcoming patch, so regenerate it.
