Kazushi (Jam) Marukawa 015dee1ac8 [VE] Support (m)0 and (m)1 operands
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.

Kazushi (Jam) Marukawa e981a46a77 [VE] Update lea/load/store instructions
Summary:
Modify lea/load/store instructions to accept `disp(index, base)`
style addressing mode (called ASX format).  Also, uniform the
number of DAG nodes to have 3 operands for this ASX format
instructions, and update selectADDR functions to lower
appropriate MI.
