Mark vector loops as already vectorized

Make sure we mark all loops (scalar and vector) when vectorizing,
so that we don't try to vectorize them anymore. Also, set unroll
to 1, since this is what we check for on early exit.

ARM: Mark double-precision instructions as such

This prevents us from silently accepting invalid instructions on (for example)
Cortex-M4 with just single-precision VFP support.

No tests for the extra Pat Requires because they're essentially assertions: the
affected code should have been lowered to libcalls before ISel.

Inliner: Handle readonly attribute per argument when adding memcpy

Patch by: Vincent Lejeune

Remove class abstraction from ARM struct byval lowering

This commit changes the struct byval lowering for arm to use inline
checks for the subtarget instead of a class abstraction to represent
the differences. The class abstraction was judged to be too much
code for this task.

No intended functionality change.

Remove unused debug-only member variable.

This may've been used at some point but the 'print' member function grew
an Indent parameter that entirely shadows this parameter.

lto.h: Use lto_bool_t instead of int to restore the ABI

This reverts commit r193255 and instead creates an lto_bool_t typedef
that points to bool, _Bool, or unsigned char depending on what is
available.  Only recent versions of MSVC provide a stdbool.h header.

MCStreamer: Reimplement the virtual EmitRawText as a protected member, EmitRawTextImpl, to avoid string literal ambiguities

Also improve the implementation of EmitRawText(Twine) so it doesn't
bother using the SmallString buffer if the Twine is a simple StringRef
anyway.

ARM: Tweak usage of '*vfp' compiler_rt functions.

Only use them if the subtarget has ARM mode, as these routines are implemented
