Fangrui Song	25e22613df	[XRay] Change ARM/AArch64/powerpc64le to use version 2 sled (PC-relative address) Follow-up of D78082 (x86-64). This change avoids dynamic relocations in `xray_instr_map` for ARM/AArch64/powerpc64le. MIPS64 cannot use 64-bit PC-relative addresses because R_MIPS_PC64 is not defined. Because MIPS32 shares the same code, for simplicity, we don't use PC-relative addresses for MIPS32 as well. Tested on AArch64 Linux and ppc64le Linux.

[XRay] Change ARM/AArch64/powerpc64le to use version 2 sled (PC-relative address)

Follow-up of D78082 (x86-64).

This change avoids dynamic relocations in `xray_instr_map` for ARM/AArch64/powerpc64le.

MIPS64 cannot use 64-bit PC-relative addresses because R_MIPS_PC64 is not defined.
Because MIPS32 shares the same code, for simplicity, we don't use PC-relative addresses for MIPS32 as well.

Tested on AArch64 Linux and ppc64le Linux.
