x86_64: allow for any index register in complex SIB encodings
...
This relieves register pressure, and reduce generated code size
(since now we can use the same index register for both `mov_scale_src`
and `mov_scale_dst` MIR instructions).
Fix lowering of ModRM + SIB encodings where index register is extended
- previously, we would carelessly ignore the fact generating incorrect
encodings.

wasm: create relocations for extern decls
...
This also fixes performing relocations for data symbols
of which the target symbol exists in an external object file.
We do this by checking if the target symbol was discarded,
and if so: get the new location so that we can find the
corresponding atom that belongs to said new location. Previously
it would always assume the symbol would live in the same file
as the atom/symbol that is doing the relocation.

coff: cleanup relocations; remove COFF support from other backends
...
Given that COFF will want to support PIC from ground-up, there is no
point in leaving outdated code for COFF in other backends such as
arm or aarch64. Instead, when we are ready to look into those, we
can start figuring out what to add and where.

stage2: explicitly tagged enums no longer have one possible value
...
Previously, Zig had inconsistent semantics for an enum like this:
`enum(u8){zero = 0}`
Although in theory this can only hold one possible value, the tag
`zero`, Zig no longer will treat the type this way. It will do loads and
stores, as if the type has runtime bits.
Closes #12619
Tests passed locally:
* test-behavior
* test-cases

wasm: fix callInstrinsic return value
...
Rather than storing it in a local and returning that,
we now keep this on the stack as all internal functions
expect it to be on the stack already and therefore were
generating extra `local.set` instructions.
