[RFC testsuite] Fix PR64850, tweak acc_on_device* tests

[Kaz Kojima <kkojima at rr dot iij4u dot or dot jp>]

Hi,

Several goacc/acc_on_device tests fail for a few targets:

hppa2.0w-hp-hpux11.11 (PR testsuite/64850)
https://gcc.gnu.org/ml/gcc-testresults/2015-01/msg02659.html

m68k-unknown-linux-gnu
https://gcc.gnu.org/ml/gcc-testresults/2015-01/msg02960.html

sh4-unknown-linux-gnu
https://gcc.gnu.org/ml/gcc-testresults/2015-01/msg02930.html

Also they fail with special options
x86_64-unknown-linux-gnu -fpic -mcmodel=large
https://gcc.gnu.org/ml/gcc-testresults/2015-02/msg00198.html

Those tests scan .expand rtl dumps to get the number of calls for
acc_on_device function.  For almost targets, the call rtx looks
something like

  (call (mem:QI (symbol_ref:SI ("acc_on_device") [flags 0x41]  <function_decl 0xb7614100 acc_on_device>) [0 acc_on_device S1 A8])

and tests use the regular expression "\\\(call \[^\\n\]*\\\"acc_on_device"
to detect it.
This expression doesn't match with the corresponding call rtx

  (call (mem:SI (symbol_ref/v:SI ("@acc_on_device") [flags 0x41]  <function_decl 0xb764d900 acc_on_device>) [0 acc_on_device S4 A32])

for hppa and something like

  (call (mem:QI (reg/f:SI 33) [0 acc_on_device S1 A8])

for m68k and sh.  All call rtxes have the function name in
the alias set of its mem rtx and it seems that the regular
expression "\\\(call \[^\\n\]* acc_on_device" works for all
cases.  The attached patch is tested on i686-pc-linux-gnu and
sh4-unknown-linux-gnu.

Regards,
	kaz
