[X86] Refactor peepholes for masked shift amount into a multiclass

The peephole (shift x, (and y, 31)) -> (shift x, y) is repeated for each
integer type and each shift variant.

To improve this a new multiclass is added that covers all integer types.  The
shift patterns are now instantiated from this.  I am planning to add new
instances for rotates as well.

No functional change intended:

  * test/CodeGen/X86/shift-and.ll provides coverage

  * Compared the expanded tablegen output and matched up the defs for these
    Pat<>s before and after

Allow switch-to-lookup table for tables with holes by adding bitmask check

This allows us to generate table lookups for code such as:

  unsigned test(unsigned x) {
    switch (x) {
      case 100: return 0;
      case 101: return 1;
      case 103: return 2;
      case 105: return 3;
      case 107: return 4;
      case 109: return 5;
      case 110: return 6;
      default: return f(x);
    }
  }

Since cases 102, 104, etc. are not constants, the lookup table has holes
in those positions. We therefore guard the table lookup with a bitmask check.

Profile: Add a library for the instrumentation based profiling format

This provides a library to work with the instrumentation based
profiling format that is used by clang's -fprofile-instr-* options and
by the llvm-profdata tool. This is a binary format, rather than the
textual one that's currently in use.

The tests are in the subsequent commits that use this.

llvm-profdata: Use the Profile library, implement show and generate

This replaces the llvm-profdata tool with a version that uses the

Reject alias to undefined symbols in the verifier.

On ELF and COFF an alias is just another name for a position in the file.
There is no way to refer to a position in another file, so an alias to
undefined is meaningless.

MachO currently doesn't support aliases. The spec has a N_INDR, which when
implemented will have a different set of restrictions. Adding support for
it shouldn't be harder than any other IR extension.

For now, having the IR represent what is actually possible with current
tools makes it easier to fix the design of GlobalAlias.
