LOG: [NFC][AIX]Disable failed tests due to aggressive byval alignment warning
on AIX
These tests emit unexpected diagnostics on AIX because the byval alignment
warning is emitted too aggressively. https://reviews.llvm.org/D118350 is
supposed to provide a proper fix to the problem, but for the time being disable
the tests to unblock.

LOG: [AIX] Check for typedef properly when getting preferred type align
The current check for typedef is naive and doesn't deal with any convoluted
cases. This patch makes use of the new 'AlignRequirement' enum field from
'TypeInfo' to determine whether or not this is an 'aligned' attribute on a
typedef.

[clang] 71b170c - [AIX] "aligned" attribute does not decrease alignment

LOG: [AIX] "aligned" attribute does not decrease alignment
The "aligned" attribute can only increase the alignment of a struct, or struct
member, unless it's used together with the "packed" attribute, or used as a
part of a typedef, in which case, the "aligned" attribute can both increase and
decrease alignment.
That said, we expect:
1. "aligned" attribute alone: does not interfere with the alignment upgrade
instrumented by the AIX "power" alignment rule,
2. "aligned" attribute + typedef: overrides any computed alignment,
3. "aligned" attribute + "packed" attribute: overrides any computed alignment.
The old implementation achieved 2 and 3, but didn't get 1 right, in that any
field marked attribute "aligned" would not go through the alignment upgrade.

[clang] 73733ae - TypeInfo records more information about align requirement

LOG: TypeInfo records more information about align requirement
Extend the information preserved in `TypeInfo` by replacing the
`AlignIsRequired` bool flag with a three-valued enum, the enum also indicates
where the alignment attribute come from, which could be helpful in determining
whether the attribute should overrule.

[clang] a919165 - [AIX] "aligned" attribute should not decrease type alignment returned by __alignof__

LOG: [AIX] "aligned" attribute should not decrease type alignment returned by
__alignof__
`__alignof__(x)` always returns `ABIAlign` if the "x" is marked
`__attribute__((aligned()))`. However, the "aligned" attribute should only
increase the alignment of a struct, or struct member, unless it's used together
with the "packed" attribute, or used as a part of a typedef, in which case, the
"aligned" attribute can both increase and decrease alignment.

LOG: [PowerPC][AIX] Fix Zero-width bit fields wrt MaxFieldAlign.
On AIX when there is a pragma pack, or pragma align in effect then zero-width
bitfields should pad out to the end of the bitfield container but not increase
the alignment requirements of the struct greater then the max field align.

LOG: [NFC] Fix formatting for the 'aix-ld.c' test case.
Summary:
Based on comments received in D80415 pertinent to test case format, the
following fixes are provided to other tests in 'aix-ld.c' for the sake of
consistency and readability,
- Align flags in RUN directives vertically.
- Align patterns in CHECK directives vertically.
- Remove the ‘-o %t.o’ as it’s unnecessary for tests with ‘-###’.
- Fix typos in comments.

[clang] 5bf2409 - [AIX] Add '-bcdtors:all:0:s' to linker to gather static init functions
Author: stevewan

New Revision: 5bf2409a4e4d23018ecffe4eff39988a957e76f7

LOG: [AIX] Add '-bcdtors:all:0:s' to linker to gather static init functions
Summary: On AIX, add '-bcdtors:all:0:s' to the linker implicitly through the
driver so that we can collect all static constructor and destructor functions.
