[ORC] Construct EPCGenericMemoryAccess from ExecutionSession. (#215097)

Construct EPCGenericMemoryAccess objects from ExecutionSessions, rather
than ExecutorProcessControl objects. This is a step towards migrating
EPCGenericMemoryAccess off of raw callSPSWrapper* calls and on to the
new Proxy objects (d99bd3ed157).

used in `getReason` method. This PR fixes:

[LoongArch][LASX] Fix fptosi/fptoui from <4 x float> to <4 x i64> (#214621)

These were lowered through a 128-bit f32 to i32/u32 conversion followed
by a sign/zero extension, which silently clamps any finite input that
does not fit in i32/u32 instead of producing the correct 64-bit integer.

Convert directly with xvftintrzl.l.s for the signed case. For the
unsigned case there is no f32 -> u64 lane conversion in LASX, so widen
to f64 first (which is exact) and convert with xvftintrz.lu.d. Both
forms use xvpermi.d to move the inputs into the low 64 bits of each
128-bit lane, as required by these lane-wise conversions.

Built and verified on Arch Linux for Loong64:
https://github.com/lcpu-club/loongarch-packages/pull/974. Both the LLVM
side and the Highway test suite that discovered the bug have passed
verification.

Git commit 0ec3860fe6d0b347e8e76b8353d0d71bd0684a0a by GitHub (on behalf of Lang Hames) on 10/08/2026 at 01:57..
[ORC] Reimplement EPCGenericMemoryAccess on RTBridge proxies (#215160)

Move EPCGenericMemoryAccess off ExecutionSession::callSPSWrapperAsync
and onto rt::Proxy objects. The FuncAddrs struct (13 ExecutorAddrs)
becomes Funcs (13 rt::Proxy members), and each access method collapses
to a single proxy call: the ProxySpec's dispatch now handles argument
serialization and the (Error, Result) -> Expected result plumbing that
was previously open-coded in each method.

Funcs members are protocol-agnostic rt::Proxy values, so a client can
populate a Funcs for a different protocol and pass it to the (public)
constructor. A new static Create(ES) provides the SPS convenience path,
resolving the proxies from the bootstrap JITDylib. The proxy types are
named once as rt::Mem*Proxy aliases in Proxy.h (beside the existing
Call*Proxy aliases) and reused by both the Funcs struct and the
memory-access ProxySpecs added to RTBridge/SPS/ProxySpecs.h.
InProcessEPC and SimpleRemoteEPC now just call
EPCGenericMemoryAccess::Create.

The executor-side wrappers registered by OrcRTBootstrap move to the
runtime's controller-interface names (orc_rt_ci_sps_mem_*), matching the
SPS controller interface that Create resolves against, so the in-tree
executor and controller agree on the same names. The now-dead
Memory*WrapperName constants are removed from OrcRTBridge.
