This cc1 option -fallow-half-arguments-and-returns allows __fp16 to be

currently always enabled for Arm and AArch64, by forcing the option in

arm_neon.h) need to specify the option too, to prevent the error from
being emitted.
This changes it to a target option instead, set to true for Arm and
AArch64. This allows the option to be removed. Previously it was implied
by -fnative_half_arguments_and_returns, which is set for certain
languages like open_cl, renderscript and hlsl, so that option now too
controls the errors. There were are few other non-arm uses of

[InstrProfiling] Fix emitting runtime hook once
https://reviews.llvm.org/D134254 introduced an issue on Fuchsia
target, which does not unconditionally emit runtime hook.
It used containsProfilingIntrinsics(M) after intrinsics are lowered.
So, this patch fixes the issue by capturing the result of that
function invocation before intrinsics are lowered.

[StackLifetime] More efficient loop for LivenessType::Must
CFG with cycles may requires additional passes of "while (Changed)"
iteration if to propagate data back from latter blocks to earlier blocks,
ordered according to depth_fist.
OR logic, used for ::May, converge to stable state faster then AND logic
use for ::Must.
Though the better solution is to switch to some some form of queue, but
having that this one is good enough, I will consider to do that later.
We can switch ::Must to OR logic if we calculate "may be dead" instead
of direct "must be alive" and then convert values to match existing
interface.
Additionally it fixes correctness in "@cycle" test.

[AArch64][GlobalISel] Make G_PTRTOINT only legal for s64 + p0
A few issues:
1. There was no legalizer test for G_PTRTOINT
2. Same clamping issue as in many other opcodes
3. AArch64 pointers can only be 64b, so in reality we always have to trunc or
extend with any size other than p0 anyway.
This seems to actually produce more correct selection for narrow types as well.

[AArch64][GlobalISel] Implement custom legalization for s32/s64 G_FCOPYSIGN
This is intended to be equivalent to the s32 + s64 cases in

Widen everything and then use G_BIT + a mask to handle the actual copysign
operation. Then, narrow back down to s32/s64.
I wasn't sure about what the best/most canonical INSERT_SUBREG-selectable
pattern is. I chose G_INSERT_VECTOR_ELT + an undef vector because it produces
reasonably okay codegen. (It doesn't produce INSERT_SUBREG right now though.)
If there's a better way to do this then I'm happy to change it.
We also have a couple codegen deficiencies with how we emit vector constants
right now. (We need a GISel equivalent to the tryAdvSIMDModImm64 stuff)

When there are variable errors, display an error in VS Code's local variables view.
After recent diffs that enable variable errors that stop variables from being correctly displayed when debugging, allow users to see these errors in the LOCALS variables in the VS Code UI. We do this by detecting when no variables are available and when there is an error to be displayed, and we add a single variable named "<error>" whose value is a string error that the user can read. This allows the user to be aware of the reason variables are not available and fix the issue. Previously if someone enabled "-gline-tables-only" or was debugging with DWARF in .o files or with .dwo files and those separate object files were missing or they were out of date, the user would see nothing in the variables view. Communicating these errors to the user is essential to a good debugging experience.
