MSVC linker accepts native ARM64 object files as input with `-machine:arm64ec`, similar to `-machine:arm64x`. Its usefulness is very limited; for example, both exports and imports are not reflected in the PE structures and can't work. However, their symbol tables are otherwise functional. Since we already have handling of multiple symbol tables implemented for ARM64X, the required changes are mostly about adjusting relevant checks to account for them on the ARM64EC target. Delay-load helper handling is a bit of a shortcut. The patch never pulls it for native object files and just ensures that the code is fine with that. In general, I think it would be nice to adjust the driver to pull it only when it's actually referenced, which would allow applying the same logic to the native symbol table on ARM64EC without worrying about pulling too much.

Runtime pseudo relocation list header at 0x401c, consisting of 0x0, 0x0, 0x1.
|
|
The first runtime pseudo relocation is from an x86_64 object file, with import
|
|
from 0x3000, applied at 0x7000 with a size of 64 bits. The second pseudo
|
|
relocation is from an ARM64EC object file, with import from 0x3000, applied
|
|
at 0x7008 with a size of 64 bits.
