llc/test: Use a portable way to set timeval variables

Using complex initialiser lists doesn't seem to work well with Debian
Squeeze.

This commit changes the initialisation to use separate assignments
instead.

Fixes: Jenkins #601, #602
Addresses:
  CXX    LlcTest.o
  ../../tests/llc/LlcTest.cpp: In function 'void test_llc_meta()':
  ../../tests/llc/LlcTest.cpp:137: error: expected primary-expression
  before '.' token
  ../../tests/llc/LlcTest.cpp:137: warning: extended initializer
  lists only available with -std=c++0x or -std=gnu++0x
