d730fd95ee gcc: Enable bits for sanitizer support on FreeBSD x86_64 
This patch add the necessary bits to suport libasan on FreeBSD x86_64.

gcc
	* config/i386/i386.h: Define a new macro: SUBTARGET_SHADOW_OFFSET.
	* config/i386/i386.c (ix86_asan_shadow_offset): Use this macro.
	* config/i386/darwin.h: Override the SUBTARGET_SHADOW_OFFSET macro.
	* config/i386/freebsd.h: Likewise.
	* config/freebsd.h (LIBASAN_EARLY_SPEC): Define.
	LIBTSAN_EARLY_SPEC): Likewise. (LIBLSAN_EARLY_SPEC): Likewise.

libsanitizer:

	* configure.tgt: Add x86_64- and i?86-*-freebsd* targets.

63cc547f6d Darwin, libsanitizer: Adjust minimum supported Darwin version (PR93731). 
The current imported libsanitizer code produces kernel panics for
Darwin 11 (macOS 10.7) and is unsupported for earlier versions already.

It is not clear if the current sources are even intended to be supported
on Darwin 11, so this patch causes the default to be build without
sanitizers for Darwin <= 11.

	PR sanitizer/93731
	* configure.tgt (x86_64-*-darwin*, i?86-*-darwin*): Enable by
	default only for Darwin versions greater than 12 (macOS 10.8).

additional patches.

45d53c679a [ARM/FDPIC v6 03/24] [ARM] FDPIC: Force FDPIC related options unless -mno-fdpic is provided 
In FDPIC mode, we set -fPIE unless the user provides -fno-PIE, -fpie,
-fPIC or -fpic: indeed FDPIC code is PIC, but we want to generate code
for executables rather than shared libraries by default.

We also make sure to use the --fdpic assembler option, and select the
appropriate linker emulation.

At link time, we also default to -pie, unless we are generating a
shared library or a relocatable file (-r). Note that static link is
not supported as it requires specifying the dynamic linker because the
executable still has to relocate itself at startup.

We also force 'now' binding since lazy binding is not supported.

We should also apply the same behavior for -Wl,-Ur as for -r, but I
couldn't find how to describe that in the specs fragment.
