Subject: [libc++][PSTL] Make the PSTL submodules only have one header
X-Git-Tag: upstream/17.0.6~8584
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f0917e92697d1a0157322e36557ccfa07df394ba;p=platform%2Fupstream%2Fllvm.git

[libc++][PSTL] Make the PSTL submodules only have one header

Module map generation for the private detail headers is easier done if each private header is by itself in a submodule. Move the __algorithm/pstl_backends into their own submodules.
