a9d564a8bc Combine bracedString into getSingleUnmodifiedVariable 
Everywhere we used getSingleUnmodifiedVariable, we just called bracedString on
the result. Move this into that function instead, and rename it accordingly.

eecd003e2d Optimize patterns in checkFindNameGlob 
1. Instead of pattern-matching the same list multiple times, do it only
   once and then pass the pieces separately.
2. Don't reconstruct an object equivalent to one we just deconstructed.

aa3b709b5d Track whether braces were present in T_DollarBraced 
References of the form $var and ${var} both map to the same structure in
the AST, which prevents any later analysis functions from distinguishing
them.  In preparation for adding checks that need this info, add a Bool
to T_DollarBraced that tracks whether the braces were seen at parsing
time and update all references so that this change is a no-op.
