Add benchmark for case conversion.
The base benchmarks using ICU4C are as follows.
_toLowerCaseAsciiUs 11.28 ====================
_toUpperCaseAsciiUS 11.15 ====================
_toUpperCaseLat1SuplFr 12.27 ======================
_toUpperCaseLatExtACz 13.92 =========================
_toUpperCaseLatExtBPinyin 16.35 ==============================
Temporarily changing ICU.toUpperCase to call
icu.lang.UCharacter.toUpperCase
_toLowerCaseAsciiUs 11.19 ===
_toUpperCaseAsciiUS 17.33 ====
_toUpperCaseLat1SuplFr 40.18 ===========
_toUpperCaseLatExtACz 69.09 ===================
_toUpperCaseLatExtBPinyin 108.47 ==============================
