[PATCH] gas: Add a macro test for parenthesis arguments

[H.J. Lu]

Since we must support:

	.macro test arg1, arg2
	.byte \arg1
	.byte \arg2
	.endm

	.data
 	test  0x10 + 0, 0x10 + 1

and can't support:

	.macro test arg1, arg2
	.byte \arg1
	.byte \arg2
	.endm

	.data
 	test  (0x10 + 0) (0x10 + 1)

at the same time, add a test for latter.

	PR gas/32073
	* testsuite/gas/macros/arg2.l: New file.
	* testsuite/gas/macros/arg2.s: Likewise.
	* testsuite/gas/macros/macros.exp: Run arg2.
