Several LAPACK, BLAS, and CBLAS source files defined a local statement
function named ABS1 for the complex 1-norm approximation:
ABS1( X ) = ABS( REAL( X ) ) + ABS( AIMAG( X ) )
ABS1( X ) = ABS( DBLE( X ) ) + ABS( DIMAG( X ) )
The majority of the codebase already uses CABS1 for this identical
purpose. This commit renames ABS1 to CABS1 in all remaining files
(definition line, declaration line, and all call sites within the
same file) to make the naming consistent across the repository.
A small number of fixed-form lines required continuation-line splits
to stay within the 72-column limit after the rename.
No numerical change. Statement functions are file-local in Fortran,
so there is no ABI or interface impact.
This is a preparatory cleanup before inlining these statement
functions (see issue #1200).
