jemalloc related segfault on windows

[DemonOne]

Any rust built exe file sometimes crashes on my system with segfault caused by RtlpWaitOnCriticalSection(), the call originates from jemalloc_constructor().

This happens with any file I build and even with the delivered cargo.exe, but it never seems to happen with rustc.exe

OS: Win 7 SP1

Rust version:
rustc 1.3.0 (9a92aaf 2015-09-15)
binary: rustc
commit-hash: 9a92aaf
commit-date: 2015-09-15
host: x86_64-pc-windows-gnu
release: 1.3.0

-Note: this also happens with rustc 1.2.0

Call stack:
ntdll.dll!RtlpWaitOnCriticalSection()
ntdll.dll!RtlEnterCriticalSection()
rust_application1.exe!jemalloc_constructor() Line 693

Related to #14600 and #26647

Looks like it's just tyring to use an uninitialized mutex, but since we last pinned jemalloc they've updated to using SRWLOCK which has static initialization and doesn't suffer this problem. I think to fix this we just need to update jemalloc.

e.g. land #29214

#30434 landed so I believe this is now fixed

Still fails on my machine with Rust 1.6

@DemonOne That's because due to the train release system, the fixes aren't in Rust 1.6. The jemalloc upgrade will be in Rust 1.7 and the disabling of jemalloc on Windows will be in Rust 1.8.
