[PATCH, Darwin, X86, testsuite] Amend scan-asms on three PIE tests.

[Iain Sandoe]

Darwin requires PIC code in order to support PIE.
Amend the test scan-asms to match this.

tested on x86_64-darwin16 and x86_64-linux-gnu 
(--target_board=unix\{-m32,-m64\}\{,-fpic\})
aplied to mainline,
thanks

        * gcc.target/i386/pr39013-1.c: Adjust scan-asms for PIE to
        account for PIC code on Darwin.
        * gcc.target/i386/pr39013-2.c: Likewise.
        * gcc.target/i386/pr64317.c: Likewise.
