r269586 changed the format of some warning messages.

Each switch in the warning message is now surrounded by single quotes.

This commit updates the regex's in arm.exp dejagnu files to match the
new format and remove the extra 20+ FAILs on excess errors that are
introduced on certain variations (e.g.
arm-eabi-aem/-marm/-march=armv7-a/-mfpu=vfpv3-d16/-mfloat-abi=softfp).

Regtested arm.exp with cross-compiler arm-none-eabi

arch13 introduced instructions to perform vector element-wise byte
swaps on the way from or to memory.  For a byte swap between vector
registers the vector permute instruction is required which needs a
permute pattern to be loaded into a vector register first.

With the current implementation there is a potential problem when the
decision for the reg-reg variant is made very late.  This patch is
supposed to fix that.

With the patch the required permute pattern is generated already in
the expander and attached to the bswap pattern as USE operand.  The
predicate in the insn_and_split pattern accepts it although the
permute constant as such is not a valid constant.  For the reg-reg
variant only the vector register constraint is used for the permute
constant forcing LRA to a) push the constant into literal pool and b)
load the literal pool constant into a vector register.

Currently, the druntime and phobos unittests are compiled as a separate
check program, then ran by the libphobos.unittest/unittest.exp script.
As PR d/89255 notes, this process lacks proper multilib handling.

As a first step, a new internal option that instructs the compiler to
put the reference to all unittest functions in another symbol has been
added.  This will allow each module to be compiled separately as a
standalone program using dg-runtest without running into collisions in
the D runtime module registry.

The epiphany-elf target aligns structs to 8 bytes, which causes the
static_assert(alignof(_Chunk) == 1) to fail.

Instead of requiring _Chunks to be positionable at any alignment, ensure
new buffers are aligned to alignof(_Chunk). Because the buffer size is a
power of two, we know that both the buffer size and sizeof(_Chunk) are
multiples of alignof(_Chunk). So is p is aligned to alignof(_Chunk) then
so is (p + size - sizeof(_Chunk)). So just ensure the new buffer is
aligned to at least alignof(_Chunk), which should already be true
because the caller requests at least alignof(max_align_t).
