This patch adds an easy way to write tests for expected multiline
output. For example we can test carets and underlines for
a particular diagnostic with:
/* { dg-begin-multiline-output "" }
typedef struct _GMutex GMutex;
^~~~~~~
{ dg-end-multiline-output "" } */
multiline.exp is used by prune.exp; hence we need to load it before
prune.exp via *load_gcc_lib* for the testsuites of the various
non-"gcc" support libraries (e.g. boehm-gc).

This patch by Richard allows for movmisalign optabs to be supported
in gimple-fold.c. This caused a bit of pain in the testsuite with strlenopt-8.c
in conjunction with the ARM support for movmisalign_optabs as the test
was coded up to do different things depending on whether the target
supported misaligned access or not. However now with unaligned access
being allowed for different levels of the architecture in the arm backend,
the concept of the helper function non_strict_align mapping identically
to the definition of STRICT_ALIGNMENT disappears.
Adjusted thusly for ARM. The testsuite/lib changes were tested with an
arm-none-eabi multilib that included architecture variants that did not
support unaligned access and architecture variants that did.
The testing matrix for this patch was:
1. x86_64 bootstrap and regression test - no regressions.
2. armhf bootstrap and regression test - no regressions.
3. arm-none-eabi cross build and regression test for
{-marm/-march=armv7-a/-mfpu=vfpv3-d16/-mfloat-abi=softfp}
{-mthumb/-march=armv8-a/-mfpu=crypto-neon-fp-armv8/-mfloat-abi=hard}
{-marm/-mcpu=arm7tdmi/-mfloat-abi=soft}
{-mthumb/-mcpu=arm7tdmi/-mfloat-abi=soft}
with no regressions.
Ok to apply ?

This adds movmisalignhi and movmisalignsi expanders when unaligned
access is allowed by the architecture. This allows the mid-end
to expand to misaligned loads and stored.
Compared code generated for the Linux kernel and
it changes code generation for a handful of files all for the better
basically by reducing the stack usage.
Tested by :
1. armhf bootstrap and regression test - no regressions.
2.. arm-none-eabi cross build and regression test for
{-marm/-march=armv7-a/-mfpu=vfpv3-d16/-mfloat-abi=softfp}
{-mthumb/-march=armv8-a/-mfpu=crypto-neon-fp-armv8/-mfloat-abi=hard}
{-marm/-mcpu=arm7tdmi/-mfloat-abi=soft}
{-mthumb/-mcpu=arm7tdmi/-mfloat-abi=soft}
Will apply to trunk once 2/2 is approved.
