New minor version.

libffi 3.8.0

New features

• FFI_TYPE_VECTOR (SIMD) type support with libffi-computed layout, for aarch64 and x86-64.
• ffi_call_plan_size — report the total memory a reusable call plan owns, for embedders that account for the memory held by long-lived plans.
• powerpc64 ELFv2 _Complex long double support for both IBM-128 (double-double) and IEEE-128 formats

Fixes

• powerpc64 big-endian ELFv2 closures returning 5-, 6-, or 7-byte structs: missing return jump-table entries produced a wrong result and leaked a libffi code pointer.
• ia64 return-value jump-table desync after the FFI_TYPE_LAST bump, which corrupted small-struct and HFA returns.
• powerpc Darwin closure returns broken by #951.
• i386 FreeBSD/OpenBSD small structs now returned in registers (1, 2, 4, or 8 bytes), matching the platform ABI and fixing a segfault on struct returns through ffi_call and closures.

Performance

• Cache the static trampoline "unsupported" verdict on hosts whose page size exceeds the trampoline table mapping, avoiding redundant re-initialization on every closure allocation (e.g. 64K-page aarch64).
