Fix vector syntax in error messages
Consolidate codes dealing with LLVM struct type
remove oldsmallintmap

Closes #4738
Fix slice printing
Report error for non constant vector repeat count

Fix issue #3645
Emacs: Update emacs mode to be more similar to the vim mode.

Copy the keyword list, and add `self` so that it is somewhat highlighted
(being liberal with the correct categories).
etc: Add a suppression for more enum instruction scheduling botches. rs=burningtree
test: Residual de-muting of the test suite. rs=demuting
test: De-~mut the test suite. rs=demuting
Revert "test: De-~mut the test suite. rs=demuting"

This reverts commit f63efdc2100ff28e2a42600641835e7bd8bde591.
auto merge of #5095 : thestinger/rust/smallintmap, r=catamorphism

Closes #4738.

The `std::smallintmap` module doesn't use an implicit @ box so I just added that explicitly for now to make porting simple.

Fix issue #3645
Stop parsing capture clauses
auto merge of #5084 : oncemoreification/rust/issue-4517, r=brson

Patch for #4517

This works for fixed vectors, but I am unclear how slices should be printed, simply '&[...]'  or...

e.i. How should regions be printed?

Note on `struct_elt`: the comment is wrong, it actually dereferences the nth element of LLVM struct type if it is a pointer. That's why `T_ptr` is removed in `callee.rs`.

auto merge of #5103 : dbaupp/rust/emacs-mode-update, r=graydon

Copy the keyword list from rust.vim, and add `self` so that it is highlighted
(being liberal with the correct categories).

I'm not quite willing to dive in to clean up the emacs code yet, but at least this gets a (more) modern syntax highlighting list.

I also deleted a test that would be entirely useless without capture clauses.
