Philippe Mathieu-Daudé dcb32f1d8f tcg: Search includes from the project root source directory 
We currently search both the root and the tcg/ directories for tcg
files:

  $ git grep '#include "tcg/' | wc -l
  28

  $ git grep '#include "tcg[^/]' | wc -l
  94

To simplify the preprocessor search path, unify by expliciting the
tcg/ directory.

Patch created mechanically by running:

  $ for x in \
      tcg.h tcg-mo.h tcg-op.h tcg-opc.h \
      tcg-op-gvec.h tcg-gvec-desc.h; do \
    sed -i "s,#include \"$x\",#include \"tcg/$x\"," \
      $(git grep -l "#include \"$x\""); \
    done

/* Virtually all hosts support 16-byte vectors. Those that don't can emulate
* them via GCC's generic vector extension. This turns out to be simpler and
* more reliable than getting the compiler to autovectorize.
*
* In tcg-op-gvec.c, we asserted that both the size and alignment of the data
* are multiples of 16.
*
* When the compiler does not support all of the operations we require, the
* loops are written so that we can always fall back on the base types.
