[PATCH 1/2] RISC-V: Add memcpy, memmove, memset and strcmp implementations optimized for size.

[Kito Cheng]

Hi Ilia:

Just few minor comment:

1. There is some trailing white space in the patch, could you clean up that?

/home/users/kito/riscv-gnu-toolchain-workspace/riscv-gnu-toolchain/.git/modules/riscv-newlib/rebase-apply/patch:101:
trailing whitespace.
#if defined(PREFER_SIZE_OVER_SPEED) || defined(__OPTIMIZE_SIZE__)
/home/users/kito/riscv-gnu-toolchain-workspace/riscv-gnu-toolchain/.git/modules/riscv-newlib/rebase-apply/patch:117:
trailing whitespace.

2. Patch conflict with current master branch, seems like you forgot
rebase with trunk before send patch.
