Partial fix for PR7267 based on comments by John McCall on an earlier patch.
This is more targeted, as it simply provides toggle actions for the parser to
turn access checking on and off. We then use these to suppress access checking
only while we parse the template-id (included scope specifier) of an explicit
instantiation and explicit specialization of a class template. The
specialization behavior is an extension, as it seems likely a defect that the
standard did not exempt them as it does explicit instantiations.

This allows the very common practice of specializing trait classes to work for
private, internal types. This doesn't address instantiating or specializing
function templates, although those apparently already partially work.

The naming and style for the Action layer isn't my favorite, comments and
suggestions would be appreciated there.

we used to generate:

  %arrayidx = getelementptr inbounds [100 x i32]* %A, i32 0, i64 %idxprom ; <i32*> [#uses=1]

which codegen'd to this code:

_foo:                                   ## @foo
## BB#0:                                ## %entry
subq $408, %rsp              ## imm = 0x198

movl (%rsp,%rax,4), %eax
addq $408, %rsp              ## imm = 0x198

This actually does matter, cutting out 2000 lines of IR from CGStmt.ll
for example.

Another interesting effect is that altivec.h functions which are dead
now get dce'd by the inliner.  Hence all the changes to
builtins-ppc-altivec.c to ensure the calls aren't dead.

  %tmp = load i32* %X.addr                        ; <i32> [#uses=1]
