[profile] Second speculative fix for Windows
VLAs in C appear to not work on Windows, so use COMPILER_RT_ALLOCA:
C:\b\slave\sanitizer-windows\llvm-project\compiler-rt\lib\profile\InstrProfilingWriter.c(264): error C2057: expected constant expression
C:\b\slave\sanitizer-windows\llvm-project\compiler-rt\lib\profile\InstrProfilingWriter.c(264): error C2466: cannot allocate an array of constant size 0
C:\b\slave\sanitizer-windows\llvm-project\compiler-rt\lib\profile\InstrProfilingWriter.c(264): error C2133: 'Zeroes': unknown size
