[SYCL][LIBCLC] Change __clc_size_t to unsigned (#4784)

This changes the `__clc_size_t` from a signed 64-bit int to an unsigned 64-bit int. 
The change results in the correct mangled name for `GroupAsyncCopy` built-ins. 

This is a proposed solution to issue #4502

[NFC] Remove accidentally committed file. (#4737)

DPC++ daily 2021-10-16

[sycl-post-link][NFC] Various small refactorings (#4731)

- Replaced `static` functions and variables with usage of anonymous namespace.
- Renamed some functions.
- Applied clang-format to most of the `sycl-post-link.cpp` file.
- Removed some unnecessary includes, added some which were missing (like `<vector>`).
- Added `const` qualifier almost everywhere.
- Updated _some_ comments to use "entry point" instead of "kernel".
  Full replace requires renaming corresponding command line options,
  which should be done in sync with the driver - I would prefer to do so
  in a separate commit.

[SYCL] Use device code cache when building kernel bundles (#4724)

The persistent device code cache, when enabled, is not used when
building the underlying native program in a kernel bundle. These changes
unify cache lookup with a fallback to program creation from
ProgramManager::getBuiltPIProgram with the program creation in
ProgramManager::build, ensuring that the latter also uses cached device
code. Likewise, ProgramManager::build will write the device code to the
persistent cache if it was not there already.

[ESIMD] Refactor esimd intrinsic mapping to BE intrinsics. (#4720)

* [ESIMD] Refactor esimd intrinsic mapping to BE intrinsics.

This patch
- makes names and parameter lists of __esimd* intrinsics match their
  @llvm.genx counterparts. The benefits are:
  * this removes the extra logical translation layer between __esimd* and
    @llvm.genx thus simplifying overall user-level esimd intrinsic translation
  * allows to reuse lots of functionality between SLM and surface memory
    accesses
- moves some of the translations and argument setting (like accessor field to
  surface index, setting scale) from LowerESIMD.cpp to the ESIMD headers, which
  simplifies code base.
- for all memory intrinsics moves host and device implementations to the same
  intrinsic function prototype separating them via __SYCL_DEVICE_ONLY__ macro
  thus avoiding duplication of the prototypes
- removes certain redundant __esimd* intrinsics, such as SLM memory accesses
  (which are normal surface accesses with special surface index 254), and
  __esimd_reduced_fmax,... which have the same functionality as usual fmax,...

This is also a preparatory step for fixing SLM memory accesses (revising vector
lengths, element types restirictions)

[ESIMD] Fix build error showed with disabled asserts (#4733)

Surprisingly Instruction->getNameOrAsOperand() is not defined when
asserts are disabled. Replaced that method usage with getName() method.
