6be2639aff runtime: store start PC in pcvalueCache
Currently, pcvalue only returns a valid start PC if cache is nil.
We're about to eliminate the cache argument and always use a pcvalue
cache, so make sure the cache stores the start PC and always return it
from pcvalue.

9869699c44 runtime: avoid relying on the unwinder in deferreturn
This CL changes deferreturn so that it never needs to invoke the
unwinder. Instead, in the unusual case that we recover into a frame
with pending open-coded defers, we now save the extra state needed to
find them in g.param.

bb5974e0cb runtime, cmd/compile: optimize open-coded defers
This CL optimizes open-coded defers in two ways:

1. It modifies local variable sorting to place all open-coded defer
closure slots in order, so that rather than requiring the metadata to
contain each offset individually, we just need a single offset to the
first slot.

2. Because the slots are in ascending order and can be directly
indexed, we can get rid of the count of how many defers are in the
frame. Instead, we just find the top set bit in the active defers
bitmask, and load the corresponding closure.

088f953fd0 all: add a few more godoc links
Over the past few months as I read the standard library's documentation
I kept finding spots where godoc links would have helped me.
I kept adding to a stash of changes to fix them up bit by bit.

The stash has grown big enough by now, and we're nearing a release,
so I think it's time to merge to avoid git conflicts or bit rot.

Note that a few sentences are slightly reworded,
since "implements the Fooer interface" can just be "implements [Fooer]"
now that the link provides all the context needed to the user.

a0c02df519 runtime/pprof: correct field alignment in machVMRegionBasicInfoData
The type machVMRegionBasicInfoData is generated from C type
vm_region_basic_info_data_64_t, which is a packed struct with a
64-bit field at offset 20. We cannot use uint64 as the field type
in the Go struct, as that will be aligned at offset 24, which does
not match the C struct. Change back to [8]byte (which is what the
cgo command generates), but keep the name Offset.

611706b171 cmd/compile: don't use BTS when OR works, add direct memory BTS operations
Stop using BTSconst and friends when ORLconst can be used instead.
OR can be issued by more function units than BTS can, so it could
lead to better IPC. OR might take a few more bytes to encode, but
not a lot more.

Still use BTSconst for cases where the constant otherwise wouldn't
fit and would require a separate movabs instruction to materialize
the constant. This happens when setting bits 31-63 of 64-bit targets.

Add BTS-to-memory operations so we don't need to load/bts/store.

Fixes #61694

51cb12e83b runtime: add deferreturn fast path for linked defers
A consequence of go.dev/cl/513837 was that calling deferreturn would
now use the unwinder to find (just) the current frame, and it turns
out there are workloads where this has a significant performance
impact.

As a simple optimization, this CL adds a fast path for deferreturn to
detect when there are pending linked defers, which allows us to skip
invoking the unwinder entirely.

Notably, this still doesn't handle the corner case of calling
deferreturn in a function that uses linked defer when dynamically
there just aren't any defers pending. It also means that after
recovering from a panic and returning to a frame that used open-coded,
we still need to use the unwinder too.

I hope to further optimize defer handling to improve these cases too,
but this is an easy, short-term optimization that relieves the
performance impact to the affected workloads.

9ff0116229 cmd/asm,cmd/internal/obj/riscv,cmd/link: improve TLS handling on riscv64
The existing Thread Local Storage (TLS) implementation for riscv64 uses
initial-exec (IE) mode, however a MOV of a TLS symbol currently loads the
thread pointer offset and not the actual address or memory location.

Rework TLS on riscv64 to generate the full instruction sequence needed to
load from or store to a TLS symbol. Additionally, provide support for both
initial-exec (IE) and local-exec (LE) TLS - in many cases we can use LE,
which is slightly more efficient and easier to support in the linker.
