7453f56e67 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

af19909b9c stage2: fix generic function cleanup 
When removing generic function instantiations from monomorphed_funcs, we
need to first make sure the function is generic, otherwise the hash map
tries to access the `hash` field of the function which is undefined.

cee82c7ce4 improved ABI alignment/size for >= 128-bit integers 
* riscv64: adjust alignment and size of 128-bit integers.
 * take ofmt=c into account for ABI alignment of 128-bit integers and
   structs.
 * Type: make packed struct support intInfo
 * fix f80 alignment for i386-windows-msvc

933436dc52 stage2: remove destroyed functions from maps 
This is likely the cause of the flaky test failures in master branch.
Since we have some test coverage for incremental compilation, it's not
OK to leave proper memory management of Fn objects as "TODO".

stage2: Implement explicit backing integers for packed structs 
Now the backing integer of a packed struct type may be explicitly
specified with e.g. `packed struct(u32) { ... }`.

Removed param_names from Fn inside Module.zig 
Removed the copy of param_names inside of Fn and changed to
implementation of getParamName to fetch to parameter name from the ZIR.
The signature of getParamName was also changed to take an additional
*Module argument.

4a28c1d5c3 stage2: lower each struct field type, align, init separately 
Previously, struct types, alignment values, and initialization
expressions were all lowered into the same ZIR body, which caused false
positive "depends on itself" errors when the initialization expression
depended on the size of the struct.

This also uses ResultLoc.coerced_ty for struct field alignment and
initialization values. The resulting ZIR encoding ends up being roughly
the same, neither smaller nor larger than previously.
