This catches places where a function without a prototype is
accidentally used, potentially passing an incorrect number of
arguments, and is a follow-up to the work done in
https://reviews.llvm.org/D122895 and described in the RFC
(https://discourse.llvm.org/t/rfc-enabling-wstrict-prototypes-by-default-in-c).
The diagnostic is grouped under the new -Wdeprecated-non-prototypes
warning group and is enabled by default.
The diagnostic is disabled if the function being called was implicitly
declared (the user already gets an on-by-default warning about the
creation of the implicit function declaration, so no need to warn them
twice on the same line). Additionally, the diagnostic is disabled if
the declaration of the function without a prototype was in a location
where the user explicitly disabled deprecation warnings for functions
without prototypes (this allows the provider of the API a way to
disable the diagnostic at call sites because the lack of prototype is
intentional).
Similar to the existing pattern for reodering cast(transpose),
this makes transpose following transpose and increases the chance
of embedding the transposition inside contraction op. Actually
cast ops are just special instances of elementwise ops.

When untagging the stack, the compiler may emit a sequence like:
```
.LBB0_1:
st2g sp, [sp], #32
sub x8, x8, #32
cbnz x8, .LBB0_1
stg sp, [sp], #16
```
These stack adjustments cannot be described by CFI instructions.
This patch disables merging of SP update with untagging, i.e. makes the
compiler use an additional scratch register (there should be plenty
available at this point as we are in the epilogue) and generate:
```
mov x9, sp
mov x8, #256
stg x9, [x9], #16
.LBB0_1:
sub x8, x8, #32
st2g x9, [x9], #32
cbnz x8, .LBB0_1
add sp, sp, #272
```
Merging is disabled only when we need to generate asynchronous unwind
tables.

Subj, or on other words, we have a lot of tests that are driven by
the LoopVectorizer's debug output, but we don't have
any meaningful way to autogenerate checklines in them,
which means that an insurmountable amount of manual work
is required when modifying the appropriate cost models.
That is not sustainable, so this presents a solution.

Similar to D122281, we should firstly exclude all scalable vector extending
stores and then selectively enable those which we directly support.
Also merge integer and float scalable vector into scalable_vector_valuetypes.

In order to increase parallism, certain ops with regions and have the
IsIsolatedFromAbove trait will have their verification delayed. That
means the region verifier may access the invalid ops and may lead to a
crash.

When formatted input (not list-directed or NAMELIST) is in "BZ" mode,
either because a BZ control edit descriptor appeared in a FORMAT or
BLANK="ZERO" appeared in OPEN or READ, input editing must not skip
over blanks before or within the input field.

Integer materializing can generate LU12I_W, ORI, LU32I_D, LU52I_D and
ADDI_W instructions.
According to the sign-extended behavior of these instructions
(except ORI), the generated instruction sequence can be improved.
For example, load -1 into general register:
The ADDI_W instruction performs the operation that the [31:0] bit data
in the general register `rj` plus the 12-bit immediate `simm12` sign
extension 32-bit data; the resultant [31:0] bit is sign extension, then
written into the general register `rd`.
Normal sequence:
```
lu12i.w $a0, -1
ori $a0, $a0, 2048
```
Improved with sign-extended instruction:
```
addi.w $a0, $zero, -1
```

This didn't work at all before, and would assert on any frame
index. Also copy the other fields, which I believe should cover
everything. There are a few that are untested since MIR serialization
is apparently still missing them (isStatepointSpillSlot,
ObjectSSPLayout, and ObjectSExt/ObjectZExt).
To avoid clashing with names of user derived types, the redundant
syntax TYPE(intrinsic type spec) must be interpreted as a monomorphic
derived type when "intrinsic type spec" is a single word. This
affects TYPE(BYTE) and TYPE(DOUBLECOMPLEX), but not TYPE(DOUBLE COMPLEX)
in free form source.
