[patch] Use IDENTIFIER_LENGTH instead of strlen(IDENTIFIER_POINTER) in a few places

[Steven Bosscher]

Hello,

Obvious enough that I'll commit this a week or so from now, unless
someone objects.

Ciao!
Steven

gcc/
        * tree-emultls.c (prefix_name): Use IDENTIFIER_LENGTH instead of
        strlen(IDENTIFIER_POINTER).

objc/
        * objc-encoding.c (encode_aggregate_fields): Use IDENTIFIER_LENGTH
        instead of strlen(IDENTIFIER_POINTER).
        (encode_aggregate_within): Likewise.
