40587658f9 Bring in a patch from base. 
The compiler is generally free to allocate general purpose registers in
whatever order it chooses. Reasons for choosing one register before another
usually include compiled instruction size (avoidance of REX prefixes, etc.)
or usage conventions, but somehow haven't included security implications in
the compiled bytecode. Some bytecode is more useful in polymorphic ROP
sequences than others, so it seems prudent to try to avoid that bytecode
when possible.

1e680c7e7c [AArch64] Fix bug in store of vector 0 DAGCombine. 
Avoid using XZR/WZR directly as operands to split stores of zero
vectors.  Doing so can lead to the XZR/WZR being used by an instruction
that doesn't allow it (e.g. add)

0c8599f6de COMPILER_LIBCXX -> MODGCC4_CPPWANTLIB, spotted by semarie

907271051b Use "COMPILER=base gcc4" for devel/llvm to give it a chance on aarch64. 
From Brad. I haven't tested (too many hangs for ports building) but since
it currently fails because there's no gcc4 on the arch, it can't make
things worse than they already are.

26974221e5 Mark llvm as BROKEN-powerpc, it never built fine there, and we're 
uselessly wasting cpu cycles trying.

Fails when linking binaries with 'relocation truncated to fit:
R_PPC_PLTREL24' - jca@ tried to fix ld at some point, or something else
has to be whacked.

See http://build-failures.rhaalovely.net/powerpc/2017-06-03/devel/llvm.log
or http://build-failures.rhaalovely.net/powerpc/2017-04-02/devel/llvm%2C-main.log

Disable loop idiom recognition for _libc_memset and _libc_memcpy.  These are
the internal names we use in libc for memset and memcpy and having the
compiler optimize them as calls to memset and memcpy will lead to infinite
recursion.

3e62fdd5fa Use -mlong-calls on arm and powerpc to work around relocations overflow 
On those architectures the .text section of the executables is too big
for the 32M immediate branch offset.  ld --relax is supposed to fix
things on powerpc, but it is actually ineffective here.  cc -mlong-calls
creates branches instructions using a full 32 bits register; FreeBSD
uses the same workaround.

A fix for lib/csu is still needed to avoid an overflow between .init
and .fini sections.  powerpc hasn't been tested, but we know that
devel/llvm is already broken there anyway.
