ARM: correct WoA __builtin_alloca handling on O0
When performing a dynamic stack adjustment without optimisations, we would mark
SP as def and R4 as kill. This occurred as part of the expansion of a
WIN__CHKSTK SDNode which indicated the proper handling of SP and R4. The result
would be that we would double define SP as part of an operation, which is
obviously incorrect.
Furthermore, the VTList for the chain had an incorrect parameter type of i32
instead of Other.
Correct these to permit proper lowering of __builtin_alloca at -O0.

[ARM] Add earlyclobber constraint to pre/post-indexed ARM STR instructions.
The post-indexed instructions were missing the constraint, causing unpredictable STR instructions to be emitted.
The earlyclobber constraint on the pre-indexed STR instructions is not strictly necessary, as the instruction selection for pre-indexed STR instructions goes through an additional layer of pseudo instructions which have the constraint defined, however it doesn't hurt to specify the constraint directly on the pre-indexed instructions as well, since at some point someone might create instances of them programmatically and then the constraint is definitely needed.
This fixes PR20323.

[ARM] Fix AAPCS regression caused by r211898
r211898 introduced a regression where a large struct, which would
normally be passed ByVal, was causing padding to be inserted to
prevent the backend from using some GPRs, in order to follow the
AAPCS. However, the type of the argument was not being set correctly,
so the backend cannot align 8-byte aligned struct types on the stack.
The fix is to not insert the padding arguments when the argument is
being passed ByVal.

[AArch64] Implement Clang CLI interface proposal about "-march".
1. Revert "Add default feature for CPUs on AArch64 target in Clang"
at r210625. Then, all enabled feature will by passed explicitly by
-target-feature in -cc1 option.
2. Get "-mfpu" deprecated.
3. Implement support of "-march". Usage is:
-march=armv8-a+[no]feature
For instance, "-march=armv8-a+neon+crc+nocrypto". Here "armv8-a" is
necessary, and CPU names are not acceptable. Candidate features are
fp, neon, crc and crypto. Where conflicting feature modifiers are
specified, the right-most feature is used.
4. Implement support of "-mtune". Usage is:
-march=CPU_NAME
For instance, "-march=cortex-a57". This option will ONLY get
micro-architectural feature enabled specifying to target CPU,
like "+zcm" and "+zcz" for cyclone. Any architectural features
WON'T be modified.
5. Change usage of "-mcpu" to "-mcpu=CPU_NAME+[no]feature", which is
an alias to "-march={feature of CPU_NAME}+[no]feature" and
"-mtune=CPU_NAME" together. Where this option is used in conjunction
with -march or -mtune, those options take precedence over the
appropriate part of this option.

Currently the only kind of integer IR attributes that we have are alignment
attributes, and so the attribute kind that takes an integer parameter is called
AlignAttr, but that will change (we'll soon be adding a dereferenceable

In this case, we would incorrectly determine that A's macro redefines B's
