BPF: support type exist/size and enum exist/value relocations

Four new CO-RE relocations are introduced:
  - TYPE_EXISTENCE: whether a typedef/record/enum type exists
  - TYPE_SIZE: the size of a typedef/record/enum type
  - ENUM_VALUE_EXISTENCE: whether an enum value of an enum type exists
  - ENUM_VALUE: the enum value of an enum type

These additional relocations will make CO-RE bpf programs
more adaptive for potential kernel internal data structure

[FastISel] Don't transform FSUB(-0, X) -> FNEG(X) in FastISel

This corresponds with the SelectionDAGISel change in D84056.

Also, rename some poorly named tests in CodeGen/X86/fast-isel-fneg.ll with NFC.

[MLIR] Change FunctionType::get() and TupleType::get() to use TypeRange

- Moved TypeRange into its own header/cpp file, and add hashing support.
- Change FunctionType::get() and TupleType::get() to use TypeRange

Commit 47f7174ffa71d339c1a65d1dd9a2ac5ff2abc95d by sunfish
[WebAssembly] Use "signed char" instead of "char" in SIMD intrinsics.

This allows people to use `int8_t` instead of `char`, -funsigned-char,
and generally decouples SIMD from the specialness of `char`.

And it makes intrinsics like `__builtin_wasm_add_saturate_s_i8x16`
and `__builtin_wasm_add_saturate_u_i8x16` use signed and unsigned
element types, respectively.

[libFuzzer] Fix endianness issue in ForEachNonZeroByte()

The usage pattern of Bundle variable assumes the machine is little
endian, which is not the case on SystemZ. Fix by converting Bundle to
little-endian when necessary.

[SanitizerCoverage] Fix types of __stop* and __start* symbols

If a section is supposed to hold elements of type T, then the
corresponding CreateSecStartEnd()'s Ty parameter represents T*.
Forwarding it to GlobalVariable constructor causes the resulting
GlobalVariable's type to be T*, and its SSA value type to be T**, which
is one indirection too many. This issue is mostly masked by pointer
casts, however, the global variable still gets an incorrect alignment,
which causes SystemZ to choose wrong instructions to access the

[libFuzzer] Enable for SystemZ

* Add SystemZ to the list of supported architectures.

* XFAIL a few tests.

Coverage reporting is broken, and is not easy to fix (see comment in
coverage.test). Interaction with sanitizers needs to be investigated
more thoroughly, since they appear to reduce coverage in certain cases.
