Bill Wendling 85ab57ac5d Update the tests.
This update coincides with r174110. That change ordered the attributes
alphabetically.

Manman Ren 8cd99817f9 ARM byval: when type alignment is bigger than ABI alignment, instead of
disabling byval, we set realign to true.

It will perform an aligned alloca, and call memcpy to copy the byval
argument to the local variable.
Change the size threshold back to 64 bytes.

Chandler Carruth a6399a519d Apply the same fundamental fix for PR14048 as was applied for PR11905.
The issue arises when coercing to/from types of different sizes. We need
to be certain that the allocation on either end has sufficient room for
the coerced type. When it doesn't, we need to make room, copy across,
and then proceed. PR11905 handled the case of storing function arguments
back into allocas in the function prolog, this patch handles the case of
setting up the function arguments in a call expression.

This is actually significantly simpler than the fix for PR11905. It ends
up being a trivial change to create a temporary alloca when the source
is too small and memcpy across. This should preserve the compile-time
fast-isel benefits of doing gep+load sequences and avoiding FCAs.

Reviewed by Benjamin and Evgeniy (who fixed PR11905).

Jim Grosbach 2987c57924 Tests: check for target availability for target-specific tests.
Lots of tests are using an explicit target triple w/o first checking that the
target is actually available. Add a REQUIRES clause to a bunch of them. This should
hopefully unbreak bots which don't configure w/ all targets enabled.

Evgeniy Stepanov 3fae4aeae4 Fix function prolog codegen whe coerce-to type is a struct.
This changes function prolog in such a way as to avoid out-of-bounds
stack store in the case when coerce-to type has a larger storage size
than the real argument type.

Fixes PR11905.

John McCall a5efa7386a Track whether an AggValueSlot is potentially aliased, and do not
emit call results into potentially aliased slots.  This allows us
to properly mark indirect return slots as noalias, at the cost
of requiring an extra memcpy when assigning an aggregate call
result into a l-value.  It also brings us into compliance with
the x86-64 ABI.

Daniel Dunbar f812506912 ARM/APCS: Don't respect bit-field types when laying out structures.
- This fixes the last known ABI issues with ARM/APCS.

 - I've run the first 1k ABITests with '--no-unsigned --no-vector --no-complex'
   on {armv6, armv7} x {-mno-thumb, -mthumb}, and the first 10k tests for armv7
   -mthumb, for both function return types and single argument calls. These all
   pass now (they failed horribly before without --no-bitfield).

Chris Lattner 9cffdf1331 don't slap noalias attribute on stret result arguments.
This mirror's Dan's patch for llvm-gcc in r97989, and
fixes the miscompilation in PR6525.  There is some contention
over whether this is the right thing to do, but it is the
conservative answer and demonstrably fixes a miscompilation.

Daniel Dunbar 45c7ff1d79 ARM/APCS ABI: Fix some problems with bit-fields in structures. After rereading

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).
