Move duplicated code into a helper function (exposed through overload).

There's a bit of duplicated "magic" code in opt.cpp and Clang's CodeGen that
computes the inliner threshold from opt level and size opt level.

This patch moves the code to a function that lives alongside the inliner itself,
providing a convenient overload to the inliner creation.

A separate patch can be committed to Clang to use this once it's committed to
LLVM. Standalone tools that use the inlining pass can also avoid duplicating
this code and fearing it will go out of sync.

Note: this patch also restructures the conditinal logic of the computation to
be cleaner.

Try harder to evaluate expressions when printing assembly.

When printing assembly we don't have a Layout object, but we can still
try to fold some constants.

[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.
