  -----------
  IntrinsicEmitter: Change IntrinsicsToAttributesMap from uint8_t[] to uint16_t[]

We need at least 252 UniqAttributes now, which will soon overflow.
Actually with downstream backends we can easily use up the last few values.
So bump to uint16_t.

  [RISCV] Copy isUnneededShiftMask from X86.

In d2927f786e877410d90c1e6f0e0c7d99524529c5, I added patterns
to remove (and X, 31) from sllw/srlw/sraw shift amounts.

There is code in SelectionDAGISel.cpp that knows to use
computeKnownBits to fill in bits of the mask that were removed
by SimplifyDemandedBits based on bits being known zero.

The non-W shift patterns use immbottomxlenset which allows the
mask to have more than log2(xlen) trailing ones, but doesn't
have a call to computeKnownBits to fill in bits of the mask that may
have been cleared by SimplifyDemandedBits.

This patch copies code from X86 to handle more than log2(xlen)
bottom bits set and uses computeKnownBits to fill in missing bits
before counting.

  Log Message:
  -----------
  [CSSPGO] Support of CS profiles in extended binary format.

This change brings up support of context-sensitive profiles in the format of extended binary. Existing sample profile reader/writer/merger code is being tweaked to reflect the fact of bracketed input contexts, like (`[...]`). The paired brackets are also needed in extbinary profiles because we don't yet have an otherwise good way to tell calling contexts apart from regular function names since the context delimiter `@` can somehow serve as a part of the C++ mangled names.
