Fix clang warnings in PoolAlloc.cpp

Issue=127 Signed-off-by: Nicolas Capens Signed-off-by: Daniel Koch Part 4 of 5: <http://webkit.org/b/56337> Enable -Werror on ANGLE Upstream bug: <http://code.google.com/p/angleproject/issues/detail?id=127> Fixes the following static analyzer warnings: src/compiler/PoolAlloc.cpp:154:26:{154:24-154:25}{154:28-154:42}: warning: comparison of unsigned expression < 0 is always false [-Wtautological-compare,2] for (size_t x = 0; x < guardBlockSize; x++) { ~ ^ ~~~~~~~~~~~~~~ src/compiler/PoolAlloc.cpp:159:55:{159:54-159:56}{160:30-160:34}: warning: conversion specifies type 'unsigned int' but the argument has type 'size_t' (aka 'unsigned long') [-Wformat,7] sprintf(assertMsg, "PoolAlloc: Damage %s %u byte allocation at 0x%p\n", ~^ %lu fix-it:"src/compiler/PoolAlloc.cpp":{159:54-159:56}:"%lu" * src/compiler/PoolAlloc.cpp: (TAllocation::checkGuardBlock): Changed '%u' to '%lu' for size_t variable. Put for loop inside #ifdef GUARD_BLOCKS/#endif macros to fix tautological-compare warning. (TAllocation::checkAllocList): Added newline to end of file.
