[testsuite] Adding missing dg-require-profiling directives

[Richard Sandiford <rdsandiford at googlemail dot com>]

Several profiling tests fail for MIPS16.  The problem is that MIPS has
native TLS support, but the ABI has not "yet" been extended to MIPS16.
MIPS16 is supposed to be link-compatible with non-MIPS16, so we can't
use emultls, and must simply say sorry().

This patch adds dg-require-profiling to the affected tests.  The reason
I haven't just applied it as obvious is that dg-require-profiling really
seems to be a test for link-time and runtime support.  There are presumably
targets that can't link profiling code but that are nevertheless happily
compiling the tests below.  So do we want to split the directive into two?
I ask the question while hoping the answer is "no". :-)

Tested on mips64-linux-gnu.  The tests still run for normal MIPS,
but are skipped for MIPS16.
