Currently LLVM does not generate the debug info required to get complete backtraces even when functions are inlined, so that part of the `run-pass/backtrace-debuginfo.rs` test is disabled when targetting MSVC. At worst this results in missing stack frames where functions have been inlined.
The Introduction page generated by rustbook used weird relative links
like "./getting-started.html" instead of just "getting-started.html"
like on the other pages. This adversely affected Windows builds the
worst, since it generated links like ".\getting-started.html" (note the
backslash). If you then try to upload the generated book to a webserver,
you end up with 404's. See this example of what is going on with the
Introduction page links and why this PR should fix it:

Compare the links on these two pages, for instance:
https://doc.rust-lang.org/nightly/book/https://doc.rust-lang.org/nightly/book/getting-started.html
Also, fix a few whitespace issues in build.rs.
I took a stab at fixing #28064. Not sure if this all-features-in-one-example approach is the right one. Also I completely made up the terms "star globbing" and "brace expansion globbing" -- they are just called "glob-like syntax" in the reference.
Overflows in integer pow() computations would be missed if they
preceded a 0 bit of the exponent being processed. This made
calls such as 2i32.pow(1024) not trigger an overflow.
The ARM equivalents of the AArch64 are annoyingly more complicated (and some of the AArch64 ones are too).
I think I've got exposed all the x86 intrinsics from SSE to AVX2 now (at least, the ones that LLVM implements as callable intrinsics).
