This avoids allocating an overly large slice for corrupt input.
Change the saferio.SliceCap function to take a pointer to the element type,
so that we can handle slices of interface types. This revealed that a
couple of existing calls were actually incorrect, passing the slice type
rather than the element type.
No test case because the problem can only happen for invalid data. Let
the fuzzer find cases like this.

This parses the import table properly which allows for debug/pe
to extract import symbols from pecoffs linked with an import
table in a section named something other than ".idata"
The section names in a pecoff object aren't guaranteed to actually
mean anything, so hardcoding a search for the ".idata" section
is not guaranteed to find the import table in all shared libraries.
This resulted in debug/pe being unable to read import symbols
from some libraries.
The proper way to locate the import table is to validate the
number of data directory entries, locate the import entry, and
then use the va to identify the section containing the import
table. This patch does exactly this.

Prior to this CL, the compiler and assembler
were sloppy about the LSym.Type for LSyms
containing static data.
The linker then fixed this up, converting
Sxxx and SBSS to SDATA, and SNOPTRBSS to SNOPTRDATA
if it noticed that the symbol had associated data.
It is preferable to just get this right in cmd/compile
and cmd/asm, because it removes an unnecessary traversal
of the symbol table from the linker (see #14624).
Do this by touching up the LSym.Type fixes in
LSym.prepwrite and Link.Globl.
I have confirmed by instrumenting the linker
that the now-eliminated code paths were unreached.
And an additional check in the object file writing code
will help preserve that invariant.
There was a case in the Windows linker,
