[compiler-rt][libc][GPU] Fix 7 builtin unit test build failure for spirv64 targets (#236324)
When building compiler-rt builtin unit test for spirv64 target, we
encountered a bunch of build failure due to missing symbols from libm
and libc. This PR adds part of required symbols needed by those tests
which can make 7 failed unit tests to build pass.
Using following command to build llvm-project:
cmake ../llvm -G Ninja -DLLVM_ENABLE_PROJECTS="clang"
-DRUNTIMES_spirv64-unknown-unknown_LLVM_ENABLE_RUNTIMES="compiler-rt;libc"
-DLLVM_RUNTIME_TARGETS="default;spirv64-unknown-unknown"
-DRUNTIMES_spirv64-unknown-unknown_COMPILER_RT_INCLUDE_TESTS=ON
-DRUNTIMES_spirv64-unknown-unknown_COMPILER_RT_EMULATOR=/bin/true
ninja all
ninja check-compiler-rt-spirv64-unknown-unknown
Before the fix, the build result was:
Total Discovered Tests: 275
Unsupported: 125 (45.45%)
Passed : 123 (44.73%)
Failed : 27 (9.82%)

usb: support SSP and SSPx2 xHCI
Only the default PSI IDs are supported, other controllers fall back to
USB 3.0. Record the speed IDs the controller has: the root hub BOS
lists those, and a link without one uses the closest lower ID.
Per xHCI 6.2.2, take the parent hub slot ID and port number of SS and
SSP devices from the closest higher-rank hub.

usb: Add support for SSP and SSPx2 hubs
An SSP hub reports its sublink speeds in the BOS descriptor, and
Extended Port Status tells which one each port uses. Read it based on
bcdUSB, since the ports of a hub can be faster than its upstream link.
Without it, the ports are treated as SuperSpeed.
Read the speed again in usbd_req_re_enumerate(), since a link can come
back at another speed.

Revise patch submission guidelines in Contributing.md (#235729)
There have been a few people who have been confused by the single commit
rule in this document.
Meaning they think they need to rebase/squash on every commit. This
hopefully clarifies it is only for the first commit. I also took the
liberty while in this file to just remove some duplication and link to
the actual areas that provide more detail.
[BOLT] Avoid temporary sections during symbol discovery (#237150)
`discoverFileObjects()` constructs a temporary `BinarySection` for every
candidate symbol merely to test allocation flags. This is expensive for
binaries with tens of millions of symbols (e.g. large RISC-V binaries
linked with `--emit-relocs,` which retain many local symbols referenced
by relocations needed to support linker relaxation). Inspect the ELF
section flags directly and reuse the retrieved symbol flags.
[SimplifyCFG] Thread loop header edges when the loop remains canonical (#232541)
When NeedCanonicalLoop is set, foldCondBranchOnValueKnownInPredecessor
rejected all loop headers to avoid redirecting a backedge into the
middle
of a loop and forming a cycle that bypasses the header.
Allow threading when every threaded predecessor is dominated by the
header and the destination cannot reach those predecessors without
passing through the header (e.g. a latch edge branching to a loop exit).
ufshci: fix the WLUN peripheral lookup timeout
The timeout in ufshci_sim_find_periph() is uint64_t, making the
comparison of timeout - ticks with zero always false. If the requested
peripheral does not become available, the lookup can wait indefinitely.
Use an sbintime_t deadline based on sbinuptime() and mstosbt(), and
compare the current uptime directly with the deadline. Preserve the
successful lookup path and existing timeout cleanup.
On an HP 15-fd0118ca with Intel N150 and Samsung UFS 3.1 storage, a
kernel built from stable/15 revision 84aa3cb3204d with this change
logged the missing-WLUN timeout, attached da0 and mounted root in two
boot trials.
