the adjustment is 4 in 32-bit mode.

In the epilogue, takes care to pop to a caller-saved register that's not live
at the exit (either return or tailcall instruction).

(clang/include/clang/Basic/StmtNodes.td, for instance, is tablegenned
from clang/include/clang/AST/CMakeLists.txt) so it is not contained on
the list of all .td files on the current source directory which is
used as the DEPENDS of the custom command. We must add the .td file to
the DEPENDS list of the custom command. Otherwise some .inc files are
not regenerated when the corresponding .td file changes.

When we are in code-completion mode, skip parsing of all function bodies except the one where the
code-completion point resides.

For big .cpp files like 'SemaExpr.cpp' the improvement makes a huge difference, in some cases cutting down
code-completion time -62% !

We don't get diagnostics for the bodies though, so modify the code-completion tests that check for errors.
