Define stdint.h macros unconditionally

Browse Source 
Similar to glibc, define all the stdint.h macros such as `SIZE_MAX`,
`UINT64_C`, etc unconditionally. I.e. no longer check whether
`__STDC_CONSTANT_MACROS` or `__STDC_LIMIT_MACROS` are defined. See also
<https://sourceware.org/bugzilla/show_bug.cgi?id=15366>.

This is part of reverting base 00bee6fcd7, which reverted an upstream
libc++ commit that eliminated libc++'s stdint.h wrapper header.
