Improve code completion in failure cases in two ways:
1) Suppress diagnostics as soon as we form the code-completion
token, so we don't get any error/warning spew from the early
end-of-file.
2) If we consume a code-completion token when we weren't expecting
one, go into a code-completion recovery path that produces the best
results it can based on the context that the parser is in.

If a function definition has any sort of weak linkage, its static local
variables should have that linkage. Otherwise, its static local
variables should have internal linkage. To avoid computing this excessively,
set a function's linkage before we emit code for it.
Previously we were assigning weak linkage to the static variables of
static inline functions in C++, with predictably terrible results. This
fixes that and also gives better linkage than 'weak' when merging is required.

IRgen/C++: When mark vtables used, make sure to still append to the VTableUse array if we promote a vtable from being just used to having its definition required. This ensures that we properly inform the consumer about whether the vtable is required or not, previously we could fail to do so when the vtable was in the VTableUses array before the decl which marked it as required.
- I think this can be cleaned up, since this means we may notify the consumer about the vtable twice, but I didn't see an easy fix for this without more substantial refactoring.

improve the fixit for the missing : error when parsing ?:. When
there are already two spaces before the token where the : was expected,
put the : in between the spaces. This means we get it right in both

t.c:2:17: error: expected ':'
return a ? b c;
^
:
t.c:3:16: error: expected ':'
return a ? b c;

case it says to insert ":" between the spaces. This fixes rdar://8007231
