We should be putting a newly instantiated imported type in
Instantiate/doInst onto the instTypeList, so its methods/dictionaries
are instantiated. To do this, we needed a more general way to add a
type to instTypeList, so add NeedInstType(), analogous to
NeedRuntimeType(). This has the extra advantage that now all types
created by the type substituter are added to instTypeList without any
extra code, which was easy to forget. doInst() now correctly calls
NeedInstType().
This is a bit aggressive, since a fully instantiated type in a generic
function/method may never be used, if the generic method is never
instantiated in the local package. But it should be fairly uncommon for
a generic method to mention a fully instantiated type (but it does
happen in this bug).
Fixes both cases mentioned in the bug.

For lazy import resolution, there's reentrancy issue with (*Named).load
method, when "t.resolve(t)" can lead us to the same named type, thus
(*Named).load is called recursively, causing the deadlock.
The main problem is that when instantinate a type, we calculate the type
hashing, including TParams. Calling t.TParams().Len() triggers the
reentrancy call to "(*Named).load".
To fix this, just not checking TParams().Len() if we are hashing.

Loading of constants that are 12 bits or smaller is currently performed using a single
ADDIW instruction, while constants between 13 bits and 32 bits are loaded using a
LUI+ADDIW pair.
Instead, use a single ADDI instruction for the 12 bits or smaller case - this
translates to the LI pseudo-instruction, making objdump more readable and giving:
11c7c: fff00293 li t0,-1
11c80: 00000313 li t1,0
Rather than:
11c7c: fff0029b addiw t0,zero,-1
11c80: 0000031b sext.w t1,zero
In the case where a constant exceeds 12 bits, an LUI instruction is required,
however if the lower 12 bits are zero, the ADDIW instruction can be omitted.
The same applies to the case where immediate splitting is performed for other
immediate instructions.
This removes around 900 instructions from the Go binary.

Ran the following commands inside std and cmd modules:
go get -d golang.org/x/crypto@32db794688a5a24a23a43f2a984cecd5b3d8da58 # master
go mod tidy
go mod vendor
Also add the new golang.org/x/crypto/curve25519/internal/field package
(it was created in x/crypto CL 315269) to TestDependencies in go/build.
Position it next to its upstream copy, since its required dependencies
are expected to be identical.
For #36905.

Fix a buglet in relocation processing that crops up with external
linking when you have an undefined function symbol that also has a
prototype (as if it were being defined in assembly src).
Fixes#47993.

This CL simplifies riscv addition (add r, imm) to
(ADDI (ADDI r, imm/2), imm-imm/2) if imm is in specific ranges.
(-4096 <= imm <= -2049 or 2048 <= imm <= 4094)
There is little impact to the go1 benchmark, while the total
size of pkg/linux_riscv64 decreased by about 11KB.
