p256-x86_64-asm.pl: Win64 SEH face-lift.
This imports 384e6de4c7e35e37fb3d6fbeb32ddcb5eb0d3d3f and
79ca382d4762c58c4b92fceb4e202e90c71292ae from upstream.
Differences from upstream:
- We've removed a number of unused functions.
- We never imported 3ff08e1dde56747011a702a9a5aae06cfa8ae5fc, which was
to give the assembly control over the memory layout in the tables. So
our "gather" is "select" (which is implemented the same because the
memory layout never did change) and our "scatter" is in C.
