f26573fddf elf: re-use old atom slot for a trampoline to that atom 
This is the initial implementation of Jacob Young's idea of
re-using old function slots as trampolines for new function's
location. This way the trampoline is guaranteed to be aligned
to the function's alignment.

The only edge case is if an incremental update further overaligns
the function in which case we skip/delete the trampoline and
re-evaluate all references.

std.os.linux: Add clone() implementation for mips64. (#21038) 
Only for n64; no handling for n32 yet.

Also remove pointless comment about o32 in mips64 code.

d6f9972594 all: Handle spirv in addition to spirv(32,64) where applicable. 
Some of this is arbitrary since spirv (as opposed to spirv32/spirv64) refers to
the version with logical memory layout, i.e. no 'real' pointers. This change at
least matches what clang does.
