Subject: [X86] Undef the vector reduction helper macros when we're done with them.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1c510b5fefd4f4a46bde06edee1c5052fe1b0e24;p=clang

[X86] Undef the vector reduction helper macros when we're done with them.

These are implementation helper macros we shouldn't expose them to user code if we don't need to.
