[PATCH] Expand tls testsuite

[Jack Howarth <howarth at bromo dot med dot uc dot edu>]

  Currently in gcc trunk, a large number of testcases are
not configured to run against emutls. The attached patch changes
these instances of...

 dg-require-effective-target tls_native

...to...

 dg-require-effective-target tls

With these changes, all of the testcases pass on
x86_64-apple-darwin10/i386-apple-darwin10 at -m64 
with the exception of...

FAIL: gcc.dg/tls/section-1.c conflict with user-defined section (test for errors, line 12)

and on x86_64-apple-darwin10/i386-apple-darwin10 at -m32...

FAIL: gcc.dg/tls/opt-4.c scan-assembler tcc1@
FAIL: gcc.dg/tls/opt-4.c scan-assembler tcc2@
FAIL: gcc.dg/tls/opt-4.c scan-assembler-not tcc1[^@]
FAIL: gcc.dg/tls/opt-4.c scan-assembler-not tcc2[^@]
FAIL: gcc.dg/tls/section-1.c conflict with user-defined section (test for errors, line 12)

when used against the approved emutls patch...

Okay for gcc trunk after the handling of the gcc.dg/tls/opt-4.c
and gcc.dg/tls/section-1.c testcases is sorted out (i.e. should those
be skipped or left in place with PRs opened for them)?
