Correct integer constants like `1UL << 63` to `UINT64_C(1) << 63` in
order to make them work on 32-bit machines. Tested on both an i386
and x86_64 machines.

The VE backend represents vector instructions with an explicit 'i32'
vector length operand. In the VE ISA, the vector length is always read
from the VL hardware register. The LVLGen pass inserts 'lvl'
instructions as necessary to set VL to the right value before each
vector instruction.

Summary:
Add CVTSQ/CVTDQ/CVTQD/CVTQS instructions. Add regression tests for
them and other convert instructions of asmparser, mccodeemitter, and
disassembler. In order to add those instructions, support RD operands
in asmparser, mccodeemitter, and disassembler.

Summary:
Add regression tests of asmparser, mccodeemitter, and disassembler for
branch instructions. In order to support them, we enhance asmparser
by adding splitting mnemonic mechanism, e.g. "bgt.l.t" into "b", "gt",
and ".l.t", and parsing mechanism for AS style memory addressing.
We also implment encoding and decoding mechanism for branch instructions.

Summary:
Gather definitions of SDNodeXForm and change them to call C functions
instead of copying C expressions in td files. Doing this solved some
bugs in mimm detections.

Summary:
VE has special operands to represent 0b000...000111...111 (`(m)0`) and
0b111...111000...000 (`(m)1`) bit sequences. This patch supports those
operands not only in machine instructions but also in DAG lowering.

* Minimal function prologue & epilogue emission
* Instruction formats and instruction definitions as far as required for the empty function prologue & epilogue.
* I64 register class definitions.
